NASA satellite data confirmed the strengthening of Tropical Storm Marie in the Eastern Pacific Ocean. 

Using a NASA satellite rainfall product that incorporates data from satellites and observations, NASA estimated Marie's rainfall rates, reported Phys.org

Tropical Depression 18E formed on Sept. 29 by 5 p.m. EDT, southwest of the southwestern coast of Mexico, strengthening into a tropical storm and renamed Marie 12 hours later.

Tropical Storm Marie is located about 655 miles south-southwest of the southern tip of Baja California, Mexico, moving toward the west near 16 mph. According to Phys.org, a westward to west-northwestward movement is expected through Friday. 

Maximum sustained winds increased to near 65 mph with higher gusts.

NASA used its Integrated Multi-satellitE Retrievals for GPM or IMERG, a NASA satellite rainfall product, to estimate that on Sept. 30 at 5:30 a.m. EDT Tropical Storm Marie was generating between 1.2 to 1.6 inches of rain around the center of circulation. 

Heavy rainfall near the center suggests hot towering thunderstorms, according to NASA.

According to NASA research, a tropical cyclone with a hot tower in its eyewall is twice as likely to intensify within six or more hours than a cyclone that lacks a hot tower.

The IMERG rainfall data was overlaid on infrared imagery from NOAA's GOES-16 satellite to understand the full extent of the storm, reported Phys.org.

NASA satellite imagery shows that Marie's structure has been gradually improving. According to the National Hurricane Center, Marie's center is embedded beneath a central dense overcast feature and the band of thunderstorms in the western quadrant of the storm has become more pronounced and continuous. 

“Infrared and water vapor data from NASA’s Aqua, Terra and NASA-NOAA’s Suomi NPP satellite were used to help forecasters assess the environment where Marie was headed,” said NASA. 

According to NHC Hurricane Specialist Robbie Berg, Tropical Storm Marie will rapidly intensify during the next couple of days. 

The National Hurricane Center expects rapid strengthening and Marie is expected to become a major hurricane by Oct. 1.
