The abrupt cutoff of satellite data crucial for hurricane forecasting is delayed by one month, until July 31, according to a message posted by the National Oceanic and Atmospheric Administration Monday.
The impending data loss from a Department of Defense weather satellite system was announced on June 25 and slated to take place 'no later than' Monday, according to an earlier NOAA announcement.
The Defense Department will still maintain the Defense Meteorological Satellite program, but announced last week it would cease sharing the imagery with NOAA and NASA.
The decision, which was initiated by the Defense Department, caused an uproar among meteorologists, public officials and the media in the midst of hurricane season. The fear is that the missing information could degrade the accuracy of hurricane forecasts. The move comes in the wake of steep personnel cuts at the National Weather Service and other parts of NOAA.
The data in question is from a microwave sounder data known as the Special Sensor Microwave Imager Sounder, or SSMIS. This tool is like a 3D X-ray of tropical storms and hurricanes, revealing where the strongest rain bands and winds are likely to be and how they are shifting.
Such imagery provides forecasters with information about a storm's inner structure and is one of the limited ways they can discern how quickly and significantly a storm's intensity is changing, particularly at night and during periods when hurricane hunter aircraft are not flying in the storm.
According to a former NOAA employee familiar with the matter, the Defense Department's actions caught the nation's weather and oceans agency off guard, along with NASA, whose scientists also use this satellite imagery.
The delay, this source said, is the result of pressure from both NOAA and NASA officials. The new NOAA message supports this, stating: 'Late on Friday, June 27th, CNMOC received a request from Dr. Germain with NASA to postpone the removal and to continue processing and distributing DMSP data through July 31st.'
'An update service advisory will be sent and FNMOC now expects to decommission DMSP processing no later than July 31st,' the message states, referring to the Navy's Fleet Numerical Meteorology and Oceanography Center. The satellite status message references Karen M. St. Germain, the division director for NASA's Earth Science Division. This indicates the intervening of a high level official in this matter.
The one month delay does not solve the issue since hurricane season peaks in August and September, and there currently is no plan in place for resuming the flow of this data, even when a new Defense Department weather satellite begins operations in October. Currently, NOAA is planning for that microwave imagery from that satellite will flow to the agency.
According to media reports last week, the Defense Department's rationale for cutting off this data has to do with cybersecurity concerns stemming from the way the data is transmitted between agencies.
NOAA has publicly maintained there are many other sources of data on hurricanes that will allow for accurate forecasts this season.
The Atlantic hurricane season does not end until November 30, and this season is expected to be another unusually active one.
This is a developing story and will be updated.

I was the first Black man to walk in space. My career as an astronaut was hard for my family.
This as-told-to essay is based on a conversation with Dr. Bernard Harris, author of " Embracing Infinite Possibilities: Letting Go Of Fear To Reach Your Highest Potential". It has been edited for length and clarity. I was one of the original Star Trek enthusiasts. I was about 10 when the show debuted, and I would rush home each week to watch a new episode. My imagination ran wild with the idea of space and being in space. Then, when I was 13, NASA landed on the moon. When Neil Armstrong said those famous words — "one small step for man, one giant leap for mankind" — it really set my passion off. I s tudied medicine, always with the goal of becoming an astronaut. In 1990, when I was about 34, I was selected for the astronaut program. Over the next four years, I flew twice into space and became the first Black man to do a space walk. My career as an astronaut was tough on my family Many people don't realize that the space shuttle weighs 5 million pounds. To haul that into space, we light five engines that produce 7.5 million pounds of thrust. Once those are ignited, you're leaving the planet in a hurry. The first time I went to space, my daughter was about 8 months old. Her mom — my life partner — had the hardest job, raising our daughter and my three stepchildren. My work took away from family time. When it was time to launch, my family watched nervously, hoping everything went right. Inside the shuttle, I was laser-focused on making sure everything went right, so I didn't have time to worry. Space was incredibly peaceful Later, when the hatch opened for my space walk, I felt like I was falling, just for a second. My brain expected to feel gravity's pull, but after a moment, I adjusted to the floating sensation. I was tethered to a robotic arm 35 feet above the space shuttle. Below, I could see the shuttle and the Earth beyond that. Surrounding it all was the clearest view of the Milky Way galaxy that you could ever imagine. It was an incredible view for a human. I was struck by the silence. With no air to transmit sound, space is completely quiet. Floating there, I had a great sense of peace. It was even more wonderful than I expected. I want to help others follow in my footsteps The year after that walk, I left NASA, but continued to work around the space industry. I also practiced medicine and saw patients at community clinics. That's been an important way for me to give back. I've had experiences that very few people get, particularly people of color. Part of my legacy is to translate that experience and use it to create awareness here on Earth. That means sharing my story and also helping create opportunities for other people to follow in my footsteps. I founded The Harris Foundation to focus on that legacy. Our work is structured around three pillars of success: education, health, and wealth. Health is important to me, as a physician, and I want everyone to have access to quality healthcare. In order to participate equally in the American dream, we need to build wealth, not only individually but generationally. My family was poor when I was a child, but today I have built a great deal of wealth. I hope to help others do the same. Doing so starts with education. My father only had an 11th-grade education, but my mother's college degree gave her power. It changed not only her life, but mine. I may not have been so successful if she hadn't had her education. I've seen how education can change the trajectory of a person and their descendants.

Daily Weather Update from FOX Weather: Southeast tropical trouble looms as Florida braces for flooding rain
Welcome to the Daily Weather Update from FOX Weather. It's Wednesday, July 2, 2025. Start your day with everything you need to know about today's weather. You can also get a quick briefing of national, regional and local weather whenever you like with the FOX Weather Update podcast. Millions of people in Florida and the Southeast are keeping a close eye on the weather forecast that could halt outdoor and beach plans across the region over the Fourth of July holiday weekend. In addition to the precipitation, the National Hurricane Center expects to be monitoring an area of disturbed weather for tropical development, which will become the main focus for forecasters through the weekend and into next week. Regardless of tropical development, Florida is expected to see additional flooding rain and thunderstorms through the foreseeable future. The first major surge of monsoonal moisture across southern Nevada on Tuesday brought widespread disruptions to the Las Vegas Valley, unleashing near-hurricane-force wind gusts that toppled trees, downed powerlines and contributed to a large fire that killed several animals. The National Weather Service office in Las Vegas issued the first Severe Thunderstorm Warning for Clark County at approximately 3:30 p.m. local time, alerting residents that developing storm cells had the potential to cause damage to roofs, trees and other structures due to strong winds. Although radar data showed limited rainfall, the damage reported across the region was linked to what meteorologists later confirmed were "virga bombs" or "dry microbursts." Flossie strengthened into a major hurricane (Category 3 or higher) on Tuesday, but forecasters say the powerful storm will begin to rapidly weaken on Wednesday as it continues to move away from southwestern Mexico. The National Hurricane Center said maximum sustained winds within Flossie have increased to 115 mph with higher gusts, and some additional strengthening is possible through Wednesday morning before steady to rapid weakening is set to begin later on in the day. One couple had the experience of a lifetime over the weekend, when they became engaged in front of a tornado in South Dakota. Stormchasers Bryce Shelton and Paige Berdomas were tracking tornadoes during a severe weather outbreak in the Mount Rushmore State, when they saw a beautiful twister in the distance. This was the moment when Shelton decided to finally pop the question.

Chances increase slightly for tropical development over Fourth of July. See Florida impact
Chances for something tropical developing over or near Florida in the coming days increased while you slept. There's now a 40% chance for a tropical or subtropical depression forming over the next seven days if an area of low pressure develops in the southeastern Atlantic or Gulf by the holiday weekend, according to the National Hurricane Center. ➤ Track all active storms ➤ Weather alerts via text: Sign up to get updates about current storms and weather events by location Regardless of development, the system could bring up to 6 inches of rain to some portions of Florida through the Fourth of July weekend, according to the National Weather Service. The next named storm of the 2025 Atlantic hurricane season will be Chantal. In the eastern Pacific, Hurricane Flossie — now a Category 3 storm with 115 mph winds — is moving west-northwest away from land. Weakening is expected by the end of the day, July2. Here's the latest advisory from the National Hurricane Center as of 8 a.m. July 2: An area of low pressure could develop near the southeast U.S. Atlantic or Gulf coasts by this weekend along a weakening frontal boundary, according to the National Hurricane Center. Environmental conditions appear only marginally conducive for some slow development, but a tropical or subtropical depression could form in this region over the weekend or early next week while the system moves little. Regardless of development, heavy rainfall is possible across portions of the southeast U.S., particularly across the west-central Florida coast. Formation chance through 48 hours: low, near 0 percent. Formation chance through 7 days: medium, 40 percent. "Regardless of development, heavy rainfall is possible across portions of the southeast U.S., particularly across West-Central Florida," the Florida Department of Emergency Management said. "Those heading to the beaches for the holiday weekend from northern Florida and the Alabama and Mississippi panhandles to the Carolinas are urged to monitor the forecast, as there may be rough surf and rip currents and perhaps gusty winds should a tropical depression or storm develop," said Alex DaSilva, AccuWeather lead hurricane expert, adding, "We feel the development window is from around July 4 to early next week." Factors helping prevent tropical development include wind shear and dry air, including Saharan dust moving across the Atlantic and into the Gulf. Hurricane Flossie is about 315 miles south-southeast of Cabo San Lucas, Mexico. Maximum sustained winds are near 115 mph, with higher gusts. Flossie is a Category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Little change in strength is forecast this morning, with rapid weakening expected to begin by the end of the day. All coastal watches and warnings have been discontinued. This forecast track shows the most likely path of the center of the storm. It does not illustrate the full width of the storm or its impacts, and the center of the storm is likely to travel outside the cone up to 33% of the time. This forecast track shows the most likely path of the center of the storm. It does not illustrate the full width of the storm or its impacts, and the center of the storm is likely to travel outside the cone up to 33% of the time. The hatched areas on the National Hurricane Center's tropical outlook map indicate "areas where a tropical cyclone — which could be a tropical depression, tropical storm or hurricane — could develop," said National Hurricane Center Deputy Director Jamie Rhome. The colors make it visibly clear how likely a system could develop, with yellow being low, orange medium, and red high. The National Hurricane Center generally doesn't issue tropical advisories until there is a named storm, but there is an exception. "If a system is near land and there is potential for development, the National Hurricane Center won't wait before it issues advisories, even if the system hasn't become an actual storm. This gives residents time to prepare," Rhome said. Named storms historically develop close to the U.S. in July, especially in the Gulf and off the Atlantic coast between Florida and the Carolinas. Later in the season, tropical storms and hurricanes develop out of tropical waves moving off the coast of Africa. Elsewhere in the tropics, the National Hurricane Center is monitoring five tropical waves, including two in the Caribbean: Tropical wave 1: A tropical wave has an axis along 23W in the eastern Atlantic, from the Cabo Verde Islands southward, moving west at around 11 mph. Tropical wave 2: Another eastern Atlantic tropical wave is along 39W, south of 14N, moving westward around 17 mph. Tropical wave 3: A central Atlantic tropical wave is along 48W, south of 16N, moving westward at 11 to 17 mph. Tropical wave 4: An eastern Caribbean tropical wave is along 66W, south of 16N, moving westward at around 11 mph. Tropical wave 5: A tropical wave that had been in the western Caribbean is now crossing Central America into the eastern Pacific Ocean along 86W. It is moving west at 11 to 17 mph. Florida weather forecast for July 2, 2025 Pensacola, western Panhandle: The best chance for rain today will be along and east of I-65. Highs will be in the upper 80s to lower 90s. Tallahassee, central Panhandle: Wet pattern continues into Wednesday. We're also watching the potential development of a weak low next week, but main concerns with this feature still revolve around heavy rain. Some areas could see an estimated 4 to 6 inches of rain through the holiday weekend, with localized higher amounts possible. High of 89. Jacksonville, North/Northeast Florida: Regardless of tropical cyclone development, flooding rainfall risk increases Friday through the holiday weekend. "We are currently on a 26-day streak of the Jacksonville International Airport measuring a maximum temperature of 90 degrees" or warmer," the National Weather Service Jacksonville posted on X. "This ranks as the 20th longest stretch on record for JAX. This streak will likely continue this week." Daytona Beach to Stuart, East/Central Florida: Some morning sun then increasing clouds with scattered to numerous showers and lightning storms developing. Highs range from 88 in Daytona Beach to 87 in Stuart. West Palm Beach to Naples, South/Southwest Florida: Increasing showers and thunderstorms today may result in localized flooding, especially over east coast metro areas. Expect another warm day with afternoon highs in the upper 80s to low 90s. Fort Myers to Sarasota, West/Southwest Florida: "There remains high uncertainty with this (system with tropical potential) feature, but the main impact is expected to be heavy rainfall locally into the weekend." Highs today range from 89 in Fort Myers to 86 in Sarasota. The Atlantic hurricane season runs from June 1 through Nov. 30. Ninety-seven percent of tropical cyclone activity occurs during this time period, NOAA said. The Atlantic basin includes the northern Atlantic Ocean, Caribbean Sea and Gulf of America, as the Gulf of Mexico is now known in the U.S. per an order from President Trump. NOAA and the National Hurricane Center are now using Gulf of America on its maps and in its advisories. The peak of the season is Sept. 10, with the most activity happening between mid-August and mid-October, according to the Hurricane Center. Systems currently being monitored by the National Hurricane Center include: Tropical cyclone is the generic term used by the National Weather Service, NOAA and the National Hurricane Center for any tropical system, even if it's in the tropical Atlantic basin. To be more precise, a tropical cyclone is a "rotating, organized system of clouds and thunderstorms that originates over tropical or subtropical waters and has closed, low-level circulation," NOAA sadi. Once maximum sustained winds reach 74 mph, what it is called is determined by where it originated: : for storms in the North Atlantic, central North Pacific, and eastern North Pacific. : for storms in the Northwest Pacific. : for storms in the South Pacific and Indian Ocean.
