Trump Admin Stops Collecting Data Crucial for Hurricane Predictions at the Start of Hurricane Season
Just weeks before the peak of hurricane season, the Trump administration has halted transmission of key satellite data used to predict storm intensity and track, prompting warnings that the move could "cascade into poorer forecasts" and leave coastal communities more vulnerable.
On Tuesday, the U.S. Department of Defense declared it would stop processing and transmitting microwave data collected from a trio of weather satellites jointly operated with NOAA, Local 10 News reported. These satellites provide crucial scans used by the National Hurricane Center (NHC) and others to detect storm structure, estimate intensity and track development over oceans where on-the-ground observations are limited or nonexistent.
The move was formalized the next day in a National Oceanic and Atmospheric Administration (NOAA) service change notice and will take effect by June 30.
The decision to cut off access to data from the Special Sensor Microwave Imager Sounder (SSMIS) caught both the weather and national security communities by surprise. Though no official explanation has been given, the move reportedly stems from internal Department of Defense security concerns.
As a result, nearly half of the microwave imagery used to monitor storms—especially in the Pacific, where hurricane hunting aircraft rarely operate—will go dark.
The announcement comes just weeks into hurricane season, which lasts from June 1 to November 30. Peak season typically occurs between August and October, according to NOAA.
Forecasters rely heavily on this data, especially at night and in developing systems, to detect rapid intensification or shifts in a storm's structure. Without it, experts warn, the risk of a "sunrise surprise" dramatically increases when critical overnight changes go undetected until the next day.
Former NHC chief James Franklin emphasized that the real-time imagery isn't optional, calling it essential for storm positioning and accuracy. Forecast errors caused by small initial mistakes in storm tracking can multiply over just a few days, increasing the risk for millions along the coast.

Floods Expected After Hurricane Erick Makes Landfall In Western Mexico
Hurricane Erick made landfall in the western Mexican state of Oaxaca on Thursday, the US National Hurricane Center said, having weakened to a "major" Category 3 storm that is likely to cause massive flooding and landslides. The storm was packing maximum sustained winds of 125 miles (205 kilometers) per hour as it hit just east of Punta Maldonado, the NHC said in a post on social media. By 1200 GMT, Erick was moving northwest at a speed of nearly nine miles (15 kilometers) per hour, and was expected to continue making its way inland over southern Mexico through the day. Heavy rainfall was expected to cause "life-threatening flooding and mudslides, especially in areas of steep terrain" in Oaxaca and Guerrero states, the NHC said. A "life-threatening storm surge" was expected to cause coastal flooding near where the storm made landfall. "Erick is expected to rapidly weaken over the mountains of Mexico, and the system is likely to dissipate tonight or early Friday," the center's advisory added. Mexican authorities said they were also expecting heavy rain in southernmost state Chiapas. President Claudia Sheinbaum urged people to avoid going out and advised those living in low-lying areas or near rivers to move to shelters. In Acapulco, a major port and resort city famous for its nightlife, police with bullhorns walked the beach and drove around town warning residents and holidaymakers of the storm's arrival. Some shops boarded up their windows and operators of tourist boats brought their vessels ashore. Rainfall began in the late afternoon after a sunny day on Wednesday. About 250 miles (400 kilometers) south of Acapulco, the city of Puerto Escondido and its 30,000 inhabitants braced for the hurricane's effects. Restaurants were already closed despite tourists unwilling to give up their vacations, an AFP journalist noted from the scene. "They say it's going to hit this side of the coast, so we're taking precautions to avoid having any regrets later," Adalberto Ruiz, a 55-year-old fisherman sheltering his boat, told AFP. Laura Velazquez, national coordinator of civil protection, said the government was using patrols and social media to warn people. Some 2,000 temporary shelters have been set up in Chiapas, Guerrero and Oaxaca, and hundreds of troops and electricity workers have been deployed to help with any clean-up efforts. Local authorities have suspended classes and closed ports along the coast, including the port of Acapulco, to shipping. Mexico sees major storms every year, usually between May and November, on both its Pacific and Atlantic coasts. In October 2023, Acapulco was pummeled by Hurricane Otis, a powerful Category 5 storm that killed at least 50 people. Hurricane John, another Category 3 storm that hit Acapulco in September last year, caused about 15 deaths.

Mexico: Hurricane Erick reaches category 4 as landfall nears – DW – 06/19/2025
Local authorities have urged people living in low-lying areas or near rivers to move to shelters as Hurricane Erick approaches. Forecasters warn of intense rainfall across the Mexican states of Oaxaca and Guerrero. Hurricane Erick was upgraded to a Category 4 storm early Thursday as Mexico's Pacific coast braced for it to make landfall. Erick packs maximum sustained winds of 145 mph (230 kph) and was moving northwest at 9 mph (15 kph). This makes the storm an "extremely dangerous" Category 4, according to the US National Hurricane Center (NHC). The storm was Category 1 as of Wednesday morning but has quickly climbed the scale since. Erick's projected path crept south, late on Wednesday. "On the forecast track, the center of Erick is expected to make landfall in the western portion of the Mexican state of Oaxaca or the eastern portion of the Mexican state of Guerrero this morning, and then continue inland over southern Mexico later today." the NHC said in its latest advisory. Forecasters warned that the hurricane could stengthen further before making landfall. It would then likely weaken as it moves inland. The NHC had earlier warned of "damaging winds and life-threatening flash floods to portions of southern Mexico" when Erick makes landfall. Mexico braces for Hurricane Erick With forecasters warning of intense rainfall across the Mexican states of Oaxaca and Guerrero, bringing "life-threatening flooding and mudslides," President Claudia Sheinbaum urged those living in low-lying areas or near rivers to move to shelters. Around 2,000 temporary shelters have been set up in Guerrero and Oaxaca, and hundreds of troops and electricity workers have been made ready to assist in any clean-up effort. The mountainous region along the coast is particularly prone to mudslides and there are numerous rivers that could burst their banks. In Acapulco, a major port and resort famous for its nightlife, police patrolled the beach and drove around town warning residents and holidaymakers of the storm's arrival. Evelyn Salgado, the governor of Guerrero, said Wednesday that all schools had been closed. Are hurricanes common in Mexico? Mexico experiences severe storms every year between May and November, on both its Atlantic and Pacific coasts. In September 2024, Storm John, a Category 3 storm, killed 15 people. In October 2023, Acapulco was pummeled by Hurricane Otis, a Category 5 storm that resulted in at least 50 deaths. Edited by: Rana Taha
