Extreme Weather

On the morning of 7/9/18 the GPM Core Observatory satellite flew over powerful Typhoon Maria, observing a donut-shaped eyewall that is somewhat disconnected from the rest of the storm. Maria is likely to impact southern Ryukyu Islands before making landfall in Eastern China in the next couple days.

The image above shows estimates of accumulated rainfall using IMERG (Integrated Multi-satellitE Retrievals for GPM) data formed during the period from June 28-July 6, 2018. Typhoon PRAPIROON developed in the northwest pacific Ocean east-northeast of the Philippines on June 28, 2018. PRAPIROON became a typhoon on July 2nd as it approached the Korea Strait between Japan and Korea. Stormy weather had already produced heavy rainfall in Korea and Japan before typhoon PRAPIROON moved through the area. IMERG estimates indicated that PRAPIROON and other stormy weather dumped over 512 mm (20.2 inches)

Rapidly intensifying after its genesis near Guam, Super Typhoon Maria featured winds near 130 knots as it spiraled through the waters of the Western Pacific Ocean. The DPR scan indicates deep convection in several parts of the outer bands, with the most intense precipitation rates from GMI concentrated in the eyewall. Maria is expected to continue intensifying over the next three days, then weaken slightly as it crosses through the Ryukyu Islands, possible near Okinawa. The long range forecast has it making landfall in Northern China, possibly still as a

Fabio is expected to intensify over the next 24-48 hours, but will remain over open waters throughout its lifespan, eventually dissipating. Want to see other events in STORM Event Viewer?

NASA's GPM core observatory satellite flew above tropical storm FABIO in the eastern Pacific Ocean south of Mexico on June 30, 2018 at 10:46 PM MDT (July 1, 2018 at 0446 UTC). FABIO has continued to intensify since then and the National Hurricane Center (NHC) predicts that the tropical storm will become a hurricane later today. FABIO is then expected to become a major hurricane on July 3, 2018 and reach it's peak intensity with wind speeds of about 105 kts (121 mph). Rainfall measurements by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed that FABIO

Tropical depression 09W was located in the northwest Pacific east of the Philippines when it was upgraded today to tropical storm PRAPIROON. The tropical storm is in a favorable environment for intensification. Vertical wind shear is low above the tropical cyclone and sea surface temperatures are warm below. NASA's GPM core observatory satellite had a good view of tropical storm PRAPIROON on June 29, 2018 at 0246 UTC. PRAPIROON was just barely a tropical storm with maximum sustained wind speeds estimated at about 35 kts (40.3 mph). GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation

The GPM Core observatory satellite's passed over Oklahoma on Monday, June 25, 2018 04:08 AM CDT (0508 UTC). The satellite makes measurements of precipitation with it's GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments every 95 minutes as it orbits the earth at 252.3 miles (407 km). The area covered by GPM's radar is shown in lighter shades. GPM passed directly over the center of a Mesoscale Convective System (MCS) that was moving across Oklahoma. GPM found that the MCS contained some intense storms. GPM's DPR can make accurate rainfall measurements along it

Extremely heavy rainfall caused a flash flood emergency over southern Texas this week. More than 15 inches (381 mm) of rain fell in Hidalgo County, Texas since Tuesday June 19, 2018. The Governor of Texas declared a state of emergency for six counties in South Texas Thursday afternoon. Heavy rain had ended Friday morning but occasional showers were still occurring over southern Texas. At 4:28 AM CDT Friday June 22, 2018 the National Weather Service in Brownsville, Texas issued a "Flood Warning for Urban Areas and Small Streams in... Southwestern Hidalgo County in Deep South Texas..."

A mid-level and surface trough over southern Texas is producing heavy rainfall. Heavy rainfall is expected to continue in the area through Wednesday evening. On June 19, 2018 at 3:37 PM CDT ( 2037 UTC) the GPM core observatory satellite passed over the western Gulf Of Mexico. This GPM pass revealed extreme rainfall that was being produced by a tropical disturbance in the northwestern Gulf Of Mexico. GPM's Microwave Imager (GMI) and Dual Frequency Precipitation Radar (DPR) instruments probed powerful storms that were dropping rain at a rate of 3.5 inches (88 mm) per hour. The GPM satellite's

Beneficial rainfall from hurricane Bud's remnants has spread into the Desert Southwest. This rainfall may be helpful in an area that has been experiencing exceptional drought accompanied by wildfires. Bud's rainfall may also signal the beginning of the summer monsoon over the Desert Southwest. The image above shows estimates of accumulated rainfall using IMERG (Integrated Multi-satellitE Retrievals for GPM) data generated during the period from June 9-18, 2018. This rainfall occurred during the period when Bud formed southwest of Mexico, intensified into a powerful category four hurricane
