NASA - National Aeronautics and Space AdministrationPasadena, CA – Hurricane forecasters use many different types of data to forecast a storm’s intensity and track. NASA satellites and airborne instruments, including several developed and operated by NASA’s Jet Propulsion Laboratory, Pasadena, California, contribute to scientists’ understanding of tropical cyclones and help improve forecasts.

Here are some of the latest data on Hurricane Matthew from JPL-developed satellites and instruments:

Written by Harold Pierce and Rob Gutro

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – The low pressure center that has been gyrating over the northeastern Gulf of Mexico for days has now dropped very heavy precipitation over southeastern Louisiana. The Global Precipitation Measurement mission, or GPM, core satellite gathered rainfall data on the system and looked at it in three dimensions.

Up to 10 inches (254 mm) of rain since Thursday, August 11th, has already caused flooding in parts of the state. On August 12th the National Weather Service issued flash flood warnings for many parts of southeastern Louisiana. Much of the New Orleans area is under a flood watch until Saturday morning, August 13th.

The GPM core satellite found heavy rainfall in storms on Aug. 11, 2016, at 10:26 p.m. EDT falling at a rate of over 3.9 inches (100.1 mm) per hour in one intense downpour in Louisiana. A few storm tops were reaching heights of over 9.9 miles (16 km). (NASA/JAXA/Hal Pierce)
