Tropical Storms Barry And Flossie Forecast To Form In Southern Gulf, Eastern Pacific. Warning Issued In Mexico.
The tropics have quickly come to life on either side of Mexico, and that is forecast to generate two named storms, Barry and Flossie, in the next day or so.
- The big picture: A large pocket of moisture is pushing westward through Central America and the eastern Pacific, within which there are two systems that are expected to develop. Direct impacts by a tropical system in the United States are not expected, but some moisture could reach the Southwest late in the week ahead.
- Gulf system: Previously known as Invest 91L, this was designated Tropical Depression Two by the National Hurricane Center Saturday afternoon. It is producing thunderstorms over parts of southeastern Mexico and the Bay of Campeche.
A tropical storm warning has been issued along parts of eastern Mexico's Gulf Coast from southern Tamaulipas to northern Veracruz states, including Tampico. This means tropical storm conditions are expected in these areas, in this case, Sunday into Sunday night.
It is forecast to gain enough strength to become Tropical Storm Barry, the second storm of the 2025 Atlantic hurricane season. But it doesn't have a long runway before it comes ashore in eastern Mexico by late Sunday or early Monday.
Locally flooding rainfall is likely the main threat with this system. Parts of eastern Mexico, especially near Tampico, could pick up 3 to 6 inches of rain, with isolated amounts of 10 inches, according to NOAA's Weather Prediction Center. Tropical storm force winds, some elevated surf and rip currents can also be expected along eastern Mexico's Gulf Coast.
- Pacific system: Invest 95E is expected to develop into Tropical Storm Flossie in the next day or so as it moves northwestward near or offshore of the Mexican coastline. Most computer models suggest Flossie may top out either as a tropical storm or low-end hurricane. While the forecast is still uncertain, some outer bands of rain may soak areas near Mexico's Pacific coast, leading to flash flooding. Rip currents and high surf will also likely eventually develop. Tropical moisture from this storm could be sucked northward as a burst of monsoonal moisture into the Southwestern US before July 4th.

The government cuts key data used in hurricane forecasting, and experts sound an alarm
NOAA spokesperson Kim Doster, in a statement, called it a 'routine process of data rotation and replacement' and said that the remaining data sources 'are fully capable of providing a complete set of cutting-edge data and models that ensure the gold-standard weather forecasting the American people deserve.' Get Starting Point A guide through the most important stories of the morning, delivered Monday through Friday. Enter Email Sign Up Traditional visible or infrared satellites provide data that becomes images showing the structure, intensity and temperature of a storm, according to NOAA information, along with features such as lightning. But those miss the three-dimensional details of a storm. The microwave data gives critical information that can't be gleaned from the conventional satellites, and helps peer under a regular image of a hurricane or a tropical cyclone to see what is going on inside of it. It is especially helpful at night. Advertisement The news is especially noteworthy during the ongoing hurricane season and as lesser storms have become more frequent, deadly and costly as climate change is worsened by the burning of fossil fuels. Advertisement Microwave imagery allows researchers and forecasters to see the center of the storm. Experts say that can help in detecting the rapid intensification of storms and in more accurately plotting the likely path of dangerous weather. 'If a hurricane, let's say, is approaching the Gulf Coast, it's a day away from making landfall, it's nighttime,' said Union of Concerned Scientists science fellow Marc Alessi. 'We will no longer be able to say, OK, this storm is definitely undergoing rapid intensification, we need to update our forecasts to reflect that.' Other microwave data will be available but only roughly half as much, hurricane specialist Michael Lowry said in a blog post. He said that greatly increases the odds that forecasters will miss rapid intensification, underestimate intensity or misplace the storm. That 'will severely impede and degrade hurricane forecasts for this season and beyond, affecting tens of millions of Americans who live along its hurricane-prone shorelines,' he said. University of Miami hurricane researcher Brian McNoldy called the loss of data 'alarmingly bad news' in a post on Bluesky. 'Microwave data are already relatively sparse, so any loss — even gradual as satellites or instruments fail — is a big deal; but to abruptly end three active functioning satellites is insanity.' NOAA and its National Weather Service office have been the target of several cuts and changes in President Donald Trump's second term. The Department of Government Efficiency gutted the agency's workforce, local field offices and funding. Already, hurricane forecasts were anticipated to be less accurate this year because weather balloons launches have been curtailed because of the lack of staffing.

Tropical depression forms in southern Gulf
Tropical Depression No. 2 developed in the Bay of Campeche Saturday afternoon. National Weather Service Lake Charles meteorologist Andrew Tingler said the cyclone has sustained winds of 30 mph and is moving toward the west-northwest at 7 mph. Tingler said the forecast is for the system to continue this motion into Mexico late Sunday or early Monday while slowly strengthening to a tropical storm. 'If it does become a tropical storm, the system would be named Barry,' Tingler said. 'No direct impacts are anticipated for southeast Texas or Louisiana, however an increase in moisture will allow a higher than normal coverage of afternoon thunderstorms Sunday.'

Tropical Storm Andrea Hemmed And Hawed In The Central Atlantic Bringing A Lackluster Start To Hurricane Season
After multiple days of burst and bust, Tropical Storm Andrea formed in the open Central Atlantic, kicking off the Atlantic hurricane season, but this fish storm didn't last long. Andrea moved rapidly east-northeastward at 15 to 20 mph well to the southeast and east of Bermuda. The National Hurricane Center tracked the area of low pressure that became Andrea for two days, but the storm struggled to organize at first. An increase in persistent thunderstorm activity near the center of that low allowed the NHC to deem it the first Atlantic tropical storm of 2025. Thunderstorms quickly fell apart as the storm hit chilly waters and strong wind shear. On average (1991-2020), the first Atlantic storm of the season has formed by June 20, so Andrea's formation was about right on time. Chris Dolce has been a senior digital meteorologist with for 15 years after beginning his career with The Weather Channel in the early 2000s.
