Arthur (Atlantic Ocean) Tropical Storm Arthur appears to be ramping up, and NASA's Tropical Rainfall Measuring Mission or TRMM satellite spotted heavy rainfall occurring around the storm's center on July 1 when it was centered over the Bahamas. Those heavy rains are expected to affect the southern U.S. coastline over the next several days as the National Hurricane Center expects Arthur to strengthen into a hurricane. On July 2, the NHC
AIRS image of Marie. NASA's Aqua satellite passed over Tropical Storm Marie on Aug. 21 at 20:05 UTC when it was still classified as a low pressure area. The Atmospheric Infrared Sounder or AIRS instrument aboard Aqua read cloud top temperatures in the storm, and showed cloud tops as cold as -63F/-52C around the storm's center and in bands of thunderstorms east and south of the center.
On Jan. 7 at 1400 UTC (9 a.m. EST) NASA's RapidScat instrument saw Tropical Storm Ula's strongest winds around the storm's center at 27 meters per second (60.4 mph/97.2 kph). By 2100 UTC (4 p.m. EST) on Jan. 7, sustained winds had increased from 35 to 55 knots (40 to 63.2 mph/62 to 101.9 kph) around the system and it maintained that strength on Jan. 8 at 0900 UTC (4 a.m. EST). Ula was 240 nautical miles (276.2 miles/444.5 km) west of Suva, Fiji, near 18.4 degrees south latitude and 174.2…
Odile had weakened to a tropical storm with winds of about 55 knots (63.3 mph) when the TRMM satellite flew over on September 16, 2014 at 0917 UTC (2:19 a.m. PDT). Odile was still well organized and TRMM's Precipitation Radar (PR) measured rain falling at a rate of almost 130 mm (5.1 inches) per hour northeast of the tropical storm's center of circulation. The tops of some strong thunderstorms over the Gulf of California were reaching heights of 13km (8 miles).
