National Hurricane Center now tracking 4 waves in Atlantic, Caribbean, rain from Gulf system

2 days ago

The low-pressure system bringing rain and thunderstorms across Florida the last few days is expected to move out of the Gulf inland over southeastern Texas or western Louisiana going into the weekend, ending any chances for further development, according to the National Hurricane Center's July 25 update.
"Today will be the last day of widespread heavy rainfall across the Gulf Coast," said National Weather Service meteorologist Mussie Kebede. "Troughing along the coast has offered a lifting mechanism for storm development/organization over the last few days, but should wind down as an upper ridge in the vicinity strengthens.
"1-3 additional inches of rain are anticipated from the Florida panhandle to the central Texas coast by Sunday morning. Fortunately, the threat of flash flooding remains marginal due to the relatively low rain rates, resilient soils and efficient runoff methods," the forecaster said.
Elsewhere, the NHC is now tracking four tropical waves moving westward across the Atlantic: one near the Lesser Antilles, one in the open Atlantic, a third off the coast of Africa, and a new one in the Caribbean.
It's still hot out there. Heat index values ('real feel" temperatures) are expected to reach 100-107 in different areas around the state, but there are no heat advisories in effect today. However, the unusual heat and humidity the country has suffered through the last week will continue through early next week, Labede said, while building across the Southeast and Mid-South this weekend.

The next named storm of the 2025 Atlantic hurricane season will be Dexter.
Historically, the fourth named storm of the Atlantic hurricane season arrives Aug. 15. The last two named storms of the season — Barry and Chantal — developed earlier than normal.
Here's the latest tropical advisory from the National Hurricane Center as of 8 a.m. July 25:
Where is the low-pressure area?
A broad area of low pressure located about 100 miles south of the coast of southwestern Louisiana continues to produce disorganized showers and thunderstorms. This system is moving west-northwestward toward the Texas coast, and it has limited time to develop before it moves inland tonight.
Regardless of formation, locally heavy rainfall is likely over portions of the northwestern Gulf coast during the next couple of days.
Formation chance through 48 hours: Low, 10%
Formation chance through 7 days: Low, 10%
What else is happening in the tropics?
The National Hurricane Center is tracking four tropical waves.
Tropical wave 1: A tropical wave is analyzed over the eastern Atlantic near 20W, from 17N southward moving westward at 10 to 15 kt. Isolated moderate convection is depicted just west of the wave axis.
Tropical wave 2: A central Atlantic tropical wave is near 40W, from 18N southward, moving west at 10 to 15 kt. No significant convection is active with this wave.
Tropical wave 3: A central Atlantic tropical wave is near 56W, from 18N southward, moving at 20 to 25 kt. Scattered showers and thunderstorms are active from 10N to 14N between 54W and 57W.
Tropical wave 4: A Caribbean tropical wave is analyzed near 76W, from 19N southward moving west at 25 kt. Scattered moderate convection is noted from 15N to 19N between 75W and 78W.

When is the Atlantic hurricane season?
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.

Why does NHC say 'tropical cyclone' on its maps instead of hurricane or tropical storm?
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 said.
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.
