At least eleven deaths have now been attributed to deadly hurricane Micheal. Some casualties resulted not only from Micheal's destructive winds and storm surges but also from the blinding rain that Micheal produced as it battered states from Florida northeastward through Virginia. Today tropical storm Micheal is moving out over the Atlantic Ocean and has transitioned into a powerful extratropical storm.

This rainfall accumulation analysis was derived from NASA's Integrated Multi-satellitE Retrievals data (IMERG). IMERG data were used to calculate estimates of precipitation totals from a combination of space-borne passive microwave sensors, including the GMI microwave sensor on the GPM satellite, and geostationary IR (infrared) data. IMERG data benefits from algorithms developed by NASA's Precipitation Measurement Missions (PMM) science team that supports GPM's Missions. This analysis shows IMERG rainfall accumulation estimates along Micheal's track during the period from becoming a tropical depression fourteen off the coast of the Yucatan Peninsula until it passed off the East Coast. Micheal's approximate 0000Z and 1200Z locations are shown overlaid on this analysis. IMERG rainfall accumulation data indicated that Micheal frequently produced rainfall totals greater than 10 inches (254 mm) along it's track. IMERG data indicated that the heaviest rainfall accumulation occurred off the Yucatan where were over 20 inches (512 mm) were estimated. Also of interest is the heavy rainfall that fell in less than a week with stormy weather extending from Texas to the Great Lakes.
