Bertha was a named storm for just the briefest of periods, becoming a tropical storm on the morning of Wednesday May 27th at 8:30 am EDT just one hour before it made landfall along the South Carolina coast near Charleston. After making landfall, Bertha quickly weakened into a tropical depression and was then accelerated northward by the southerly flow between a deep trough of low pressure over the Mississippi Valley to the west and a ridge of high pressure located just off the US East Coast. Because of this, rainfall totals over the Carolina’s were not very heavy. Bertha’s biggest impact actually occurred when it was still in the formation process, before it became organized enough to be named. On Monday May 25th, a trough of low pressure became established over the Florida Straits, initiating shower and thunderstorm activity in the region. Over the next day, as this trough, which extended eastward over the warm waters of the Gulf Stream and eventually led to Bertha, slowly moved northward up the Florida peninsula, it provided a focus for showers and thunderstorms, which brought heavy rains to southeast Florida.
Precipitation Processing System (PPS) servers will be down for extended maintenance from Tuesday, September 22nd through Thursday September 24th. During this time the PPS websites, the PMM Publisher API, and the GPM research data server (arthurhou) will be unavailable. The GPM near real-time server (jsimpson) and satellite data collection will not be affected. Click here to learn more.
Hurricane Irma dropped extremely heavy rain at times during it’s trek from near the Cape Verdi Islands through the northern Leeward islands, Cuba and the southeastern United States. Over 16 inches (406 mm) of rain was reported in Guantanamo, in the easternmost province of Cuba, as the category five hurricane battered the country. Almost 16 inches (406 mm) of rain was also reported at Fort Pierce on the eastern side of Florida. Charleston, South Carolina reported 6 inches (152.4 mm) of rain in 24 hour. This heavy rainfall plus storm surge flooding caused the worst flooding in Charleston since
Tropical storm Cindy was downgraded to a tropical depression after moving onshore near the Texas and Louisiana Border on Thursday June 22, 2017. Flooding was reported along the the Gulf Coast even before Cindy made landfall. The rainfall around tropical storm Cindy was asymmetrical. The majority of heavy rainfall with the tropical cyclone was located east of Cindy's center in the states along the Gulf Coast from Louisiana through the Florida Panhandle. The tropical depression continued to spread heavy rain and occasionally severe thunderstorms after it came ashore. Severe thunderstorms spawned
Extremely heavy rain has recently fallen over Florida. Over 19 inches (482 mm) of rain has fallen in southeastern Florida during the past seven days. Record rainfall has been reported in Fort Lauderdale and West Palm. This extreme rainfall has led to flooding and flight cancellations. The GPM core observatory satellite flew above southern Florida on Wednesday June 7, 2017 at 6:06 AM EDT ( 1006 UTC). Data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments revealed the intensity of rainfall within powerful storms that were drenching southern
On Wednesday May 24, 2017 severe weather affected a large area of the eastern United States. Tornadoes were reported in Florida, Georgia, South Carolina, North Carolina and Ohio. The GPM core observatory satellite flew above a line of tornado spawning storms that were moving through the Florida panhandle on May 24, 2017 at 10:26 AM EDT ( 1426 UTC). GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments collected data showing that very heavy downpours were accompanying some of these storms. The violent storms moving through the Southeast were strong but GPM's
Hurricane Matthew devastated western Haiti and killed over 1,000 people. Matthew also took the lives of at least 37 deaths in the United States with 18 deaths occurring in the state of North Carolina. Flooding is still widespread in North Carolina. Some rivers in North Carolina such as the Tar and the Neuse are still rising. This rainfall analysis was accomplished using data from NASA's Integrated Multi-satelliE Retrievals for GPM (IMERG). IMERG is a unified U.S. algorithm that provides a multi-satellite precipitation product. IMERG is run twice in near-real time with the “Early” multi
