Latest Tropical Depression One Stories

Tropical Depression 18 (TD18) formed over the southwestern Caribbean Sea at 11 a.m. EDT on Oct. 22, and NASA's TRMM satellite saw a "hot towering" thunderstorm near its center of circulation hinting that it could become a tropical storm soon. A tropical storm watch has been issued for Jamaica. When NASA's Tropical Rainfall Measuring Mission (TRMM) satellite flew over the developing TD18 early on Oct. 22 at 0040 UTC (Oct. 21 at 8:40 p.m. EDT), the satellite measured rainfall rates within...

The 16th tropical depression of the Atlantic Ocean season has formed northeast of the Bahamas and NOAA's GOES-14 satellite captured a visible image of the storm as it tracks to the southwest. NOAA's GOES-14 satellite captured a visible image of newborn Tropical Depression 16 (TD16) near the Bahamas on Oct. 11 at 7:45 a.m. EDT. TD16 appeared as a rounded area of clouds just northeast of the Bahamas and its western fringes were just off the Florida east coast. GOES-14 also showed another low...

The hurricane season in the eastern Pacific isn't over and Hurricane Kenneth serves as a reminder that the season ends November 30. NASA satellite imagery shows Kenneth more organized than it appeared on Sunday, Nov. 20 and became a late season hurricane earlier Monday, Nov. 21. Kenneth began as the thirteenth tropical depression and that formed on Saturday, November 19, about 480 miles south of Acapulco, Mexico. On Sunday, November 20 at 0300 UTC (11 p.m. EST, Nov. 19) the National...

The low pressure system called System 98A was renamed tropical depression 1A over the weekend, and its strengthening was short-lived, just as it appears on NASA satellite imagery.NASA's Aqua satellite passed over Tropical Depression 1A on June 11 at 21:29 UTC (5:29 p.m. EDT) as it still sat off of India's west-central coast. The Atmospheric Infrared Sounder (AIRS) instrument did see some strong thunderstorms in the depression at that time, that brought heavy rainfall to region near the Gir...

Hurricane season doesn't start in the Northern Atlantic Ocean until June 1, but a low pressure system doesn't seem to want to follow the calendar. There's a low pressure area with a small chance for development north-northeast of Puerto Rico, and the GOES-13 satellite captured a visible image of the storm.The National Hurricane Center (NHC) issued a Special Tropical Weather Outlook on April 20 that noted the low pressure area was located about 460 miles northeast of San Juan, Puerto Rico at...

NASA's infrared satellite imagery has confirmed that Tomas is intensifying as convection is strengthening and cloud tops within the system are getting colder.Infrared imagery helps scientists detect cold top temperatures within a tropical cyclone, and Tomas' cloud tops have grown colder over the last 24 hours. Tomas showed strong convective activity in his center as indicated by high thunderstorms that were as cold as -63 degrees Fahrenheit. The colder the cloud tops, the higher and stronger...

NASA infrared satellite data from this morning revealed that Tropical Storm Tomas has weakened into a tropical depression.Tomas is in the central Caribbean Sea headed for Haiti this weekend, and forecasters are calling for a re-intensification before it makes landfall.The National Hurricane Center (NHC) in Miami, Fla. reported at 5 a.m. EDT on Nov. 3 that hurricane hunter aircraft found an "ill-defined and elongated circulation with no tropical storm-force winds at the flight level or...

NASA's infrared satellite imagery captured high, cold, strong thunderstorms within Tropical Storm Alex over the past weekend and they are still creating heavy rainfall. Alex's center is now moving out into the southwestern Gulf of Mexico and departing the Yucatan Peninsula. Alex is moving into warm waters and is expected to strengthen into a hurricane in the next day.Today, June 28, a tropical storm warning is in effect for the coast of Belize and the east coast of the Yucatan Peninsula of...
