Tropical Cyclone Freddy first made landfall along the east coast of Madagascar just north of the town of Mananjary on Feb. 21, 2023, as a Category 3 cyclone with average winds reported at ~81 mph (130 km/h) and gusts up to ~112 mph (180 km/h). After crossing over Madagascar Freddy continued westward over the Mozambique Channel before making landfall again along the east coast of Mozambique just south of Vilankulos as a moderate tropical storm with sustained winds estimated at 50 mph. Despite being weaker at landfall, Freddy caused widespread flooding across parts of Mozambique due to the storm stalling out near the coast after making landfall. Incredibly, Freddy drifted back out over the Mozambique Channel, nearly making landfall along the southwest coast of Madagascar. It then changed direction, re-intensified, weakened, re-intensified one last time, and made landfall once again on March 11 near Quelimane, Mozambique, as a Category 1 cyclone with sustained winds reported at 90 mph.

The second edition of the Global Precipitation Measurement Mission (GPM) Mentorship program is now open for registration. Limited seats are available.

Rain gauges are plentiful around the United States, but that’s not the case elsewhere in the world – particularly over oceans and sparsely populated areas. That means scientists and other data users have to rely on satellite measurements – such as those provided by NASA’s Global Precipitation Measurement (GPM) mission – to fill in the gaps. The list of data users now includes the U.S. Air Force’s 557th Weather Wing. For the first time, the Air Force meteorology unit has integrated the Integrated Multi-satellite Retrievals for GPM (IMERG) algorithm into its operational weather forecasts and

Hurricane Nicole hit the East Coast of Florida early yesterday morning, November 10th, 2022, at 3:00 am (EST) just south of Vero Beach at North Hutchinson Island. But, unlike Hurricane Ian which came ashore in late September as a powerful Category 4 storm that devasted parts of southwest Florida, Nicole made landfall as minimal Category 1 storm. Though far less intense, Nicole has still brought some heavy rain and gusty winds to the region. Nicole originated from a non-tropical low pressure system over the southwestern Atlantic. As a result, when the National Hurricane Center (NHC) was first

The GPM Applications Team in collaboration with the University of Coimbra created the GPM Mentorship Program to support new users from established and underrepresented communities and provide tailored hands-on learning experiences in using GPM data for applications. The goal of the program is to provide an overview of using state-of-the-art satellite-based precipitation estimates, and to provide users their first experience of applying GPM data to support real-world problems. The 2022 initiative is the first edition of the mentorship program.

On Sept. 30, 2022, Hurricane Ian was approaching South Carolina, which was one day after Ian finished its west-to-east crossing of Florida. NASA has been estimating Hurricane Ian's precipitation over land and ocean, which complements the array of detailed observations collected by NOAA and other agencies of Ian's impact over land.

Hurricane Ian became one of the strongest hurricanes on record to strike Florida when it made landfall Wednesday, Sept. 28th, 2022, around 3:10 pm (EDT) as a Category 4 storm near Cayo Costa, FL, about 20 miles west-southwest of Punta Gorda on Florida’s southwest coast. This same area was hit hard by Hurricane Charley in 2004, which also made landfall as a strong Category 4 storm. Both storms passed over and were intensified by the deep, warm waters of the southeastern Gulf of Mexico. Ian originated from a tropical easterly wave that propagated westward off the coast of Africa across the
