Flood watches and warnings have been issued today for states from North Carolina through New York. Major flooding of rivers and streams is forecast in Pennsylvania as heavy rainfall continues. A Large blocking high located east of Nova Scotia and Low Pressure over the upper mid west has been funneling moisture over the Mid-Atlantic states. This weather pattern includes a strong upper level trough with it’s axis becoming oriented from the Great Lakes through the eastern Gulf Of Mexico. This resulted in a dip in the jet stream that has been transporting tremendous amounts of moisture from the

Tropical storm AMPIL was moving toward the northwest with winds of about 50 kts (57.5 mph) when the GPM core observatory satellite flew above on July 20, 2018 at 0656 UTC. Data received by the satellite's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments were used in this analysis of AMPIL's precipitation. GMI and DPR showed that the northern side of the tropical storm was nearly dry and that rain bands in that area were producing only light to moderate rainfall. Moderate to heavy precipitation was found by GPM in a rain band wrapping around the southern side of

India's southwest monsoon (summer rainy season) normally occurs between June and September. This year's monsoon has been assessed as average but India's Meteorological Department statistics show that daily mean rainfall for the country has recently been above normal. At least 15 people were killed by floods and landslides in India on Wednesday July 11, 2018. So far this year, close to 200 deaths may have resulted from India's heavy monsoon rainfall. These estimates of rainfall accumulation were constructed using data from NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG). Algorithms

After striking the Ryukyu Islands of Japan and grazing Taiwan with torrential rains, Typhoon Maria made landfall just north of the populous city of Fuzhou, China with sustained winds of 95 knots and a broad shield of precipitation. The storm appears lopsided in the GMI, with much of the deep convection offshore, however, it is still likely to bring a brief period of flooding rains to this part of China before dissipating.

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.
