TRMM

The most powerful typhoon of 2013 hit southern China with reported winds of 95.6 kts (~110 mph) killing at least 20 people. The TRMM satellite had a fairly good view on September 22, 2013 at 0923 UTC as typhoon USAGI's eye was very near the coast of southern China. TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments showed that in addition to the extreme winds reported there were areas just south of USAGI's eye where rain was falling at a rate of over 169mm/hr (~6.7 inches). TRMM sliced through USAGI and found that heights of storms within USAGI were reaching only about 12km

Mexico's Pacific and Gulf coasts were both inundated by deadly tropical rainfall at the same time. Hurricane Manuel dropped extremely heavy rainfall along Mexico's Pacific coast. At least 55 people have been reported killed in Mexico due to flooding and landslides caused by extreme rainfall. Hurricane Ingrid weakened to a tropical storm and came ashore from the Gulf Of Mexico into the state of Tamaulipas near La Pesca, Mexico on Monday September 16,2013. The approximate 0000Z and 1200Z locations of the tropical cyclones are shown overlaid in white. The TRMM-based, near-real time Multi-

The TRMM satellite again flew directly above category two typhoon USAGI, with maximum wind speeds of about 120kts (~130mph), on September 21, 2013 at 0209 UTC as USAGI was passing between Taiwan and the Philippines. Rainfall data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments are shown in this image. TRMM PR found rain falling at a rate of over 134 mm/hr (~5.2 inches) in USAGI's eye wall where radar reflectivity values of over 51dBZ were returned to the satellite. A weaker Typhoon USAGI is predicted to hit Hong Kong tomorrow with wind speeds of 80kts (~92 mph).

The most powerful typhoon of 2013 may affect the northern Philippines and southern Taiwan. What is now super typhoon USAGI formed in the open waters of the Philippine Sea about 1,000 km (~620 miles) east of the Philippines on September 16, 2013. USAGI rapidly intensified and became a typhoon yesterday. Super Typhoon USAGI had estimated maximum winds of close to 140kts (~161 mph) when the TRMM satellite had an excellent view on September 19, 2013 at 1035 UTC. A precipitation analysis from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments is shown on the left overlaid on an

As predicted by the National Hurricane Center (NHC), tropical storm Manuel became a category one hurricane yesterday evening. Manuel, located over the southern Gulf Of California, was an intensifying tropical storm with maximum wind speeds of about 50kts (~57.5 mph) when viewed by the TRMM satellite on September 18, 2013 at 1845 UTC. Manuel had intensified and was a minimal hurricane, hugging Mexico's coast, with wind speeds of about 65kts (~75.8 mph) when seen again by TRMM on September 19, 2013 at 0116 UTC. Rainfall analyses that used TRMM's Microwave Imager (TMI) and Precipitation Radar (PR

The TRMM satellite had another good daytime look at tropical storm Humberto on September 17, 2013 at 1639 UTC (12:39 PM EDT). Rainfall data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) are shown overlaid on a visible/infrared image from TRMM's Visible and InfraRed Scanner (VIRS). The most intense echo found by TRMM PR was 48.3dBZ with rain falling at a rate of 56.5mm/hr (~2.22 inches) in an area north-northeast of Humberto's center. A red tropical storm symbol shows Humberto's approximate circulation center location.

Tropical storm Humberto, located in the eastern Atlantic Ocean, had little deep convection and was classified by the National Hurricane Center (NHC) as a post-tropical cyclone on September 14, 2013. On September 16, 2013 Humberto was having bursts of strong convection and was again classified a tropical storm. Humberto was viewed during the daytime by the TRMM satellite on September 15, 2013 at 1652 UTC (12:52 PM EDT) and on September 16, 2013 at 1557 UTC (11:57 AM EDT). These TRMM orbits show the significant changes that occurred within Humberto's in less than 24 hours. In the first orbit on

Mexico's Pacific and Gulf coasts are both being inundated by tropical cyclone rainfall at the same time. Tropical storm Manuel has dropped very heavy rainfall along Mexico's Pacific coast. 21 people have been reported killed in this area due to flooding and landslides caused by extreme rainfall. At the same time hurricane Ingrid weakened to a tropical storm and came ashore from the Gulf Of Mexico into the state of Tamaulipas near La Pesca, Mexico . The approximate 0000Z and 1200Z locations of the tropical cyclones are shown overlaid in white. The TRMM-based, near-real time Multi- satellite

The TRMM satellite flew over on September 16, 2013 at 0227 UTC (10:57 PM September 16) when Ingrid was still a hurricane in the Gulf Of Mexico. Data collected by TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments show that rain was falling at a rate of over 100mm/hr (~4 inches) in strong storms near Ingrid's center.
