As Tropical Storm Lorena was nearing landfall in northwestern Mexico, NASA-NOAA's Suomi NPP satellite provided forecasters with an image of the storm. By Monday, Sept. 23, Lorena's remnants were affecting the southern U.S. and bringing heavy rainfall to Arizona.

More people die during tornadoes in the Southeast than anywhere else in the United States. And still, a lot of people have misconceptions about their risk of being impacted by tornadoes, according to a new study published in PLOS One by researchers at the University of Tennessee, Knoxville.

Tropical Storm Tapah has a huge 'tail' on NASA satellite imagery. NASA's Terra satellite captured an image of the northwestern Pacific Ocean storm that revealed a large band of thunderstorms that resemble a large tail. The NASA imagery also indicated that the storm is getting better organized.

NASA's Terra satellite is one in a fleet of NASA satellites that provide data for research. Terra captured an image of Tropical Storm Kiko in the Eastern Pacific Ocean which showed the extent of the small storm.

Two tropical cyclones are very close together near the coast of western Mexico. Hurricane Lorena was moving over the southern tip of Baja California, and Tropical Storm Mario was south of Lorena over the Eastern Pacific Ocean. NASA calculated the rainfall rates happening in both of those tropical cyclones.

NASA-NOAA's Suomi NPP satellite passed over the North Atlantic Ocean and used infrared light to obtain temperature information about Hurricane Jerry's cold cloud tops.

NASA estimated extreme rainfall over eastern Texas from the remnants of Tropical Depression Imelda using a NASA satellite rainfall product that incorporates data from satellites and observations.

Satellite data has confirmed that Humberto, once a major hurricane is now a post-tropical cyclone. NASA's Terra Satellite provided a visible image of Post-Tropical Cyclone Humberto as it continued moving in an easterly direction through the North Atlantic Ocean.
