NASA sees Tropical Storm Rosa being born and powering up quickly

When NASA's Aqua satellite flew over Tropical Depression 17E at 5:41 a.m. EDT (0951 UTC) on Tuesday, October 30, the Atmospheric Infrared Sounder (AIRS) instrument took an infrared picture of the storm.

The AIRS data showed a large, circular area of very strong convection (rising air that forms thunderstorms that make up a tropical cyclone) around the storm's center. Scientists identify the convection as strong, because the air pushes cloud tops of those thunderstorms to the top of the troposphere where temperatures are as cold as or colder than -63 Fahrenheit (-52 Celsius).

The AIRS data showed that those clouds were near that temperature, indicating they were high in the atmosphere, and when they're that high, they're powerful, and are typically indicative of heavy rainfall.

At 8 a.m. EDT (1500 UTC) the center of Tropical Storm Rosa was located near latitude 14.5 north and longitude 116.5 west. Rosa is moving toward the west-northwest near 7 mph (11 kph) away from the mainland. Rosa is expected to continue in that direction and turn more to the west in the next couple of days. Rosa's estimated minimum central pressure is 1004 millibars.

Rosa's maximum sustained winds were near 40 mph (65 kph) and the National Hurricane Center expects some strengthening later today and October 31 before weakening on November 1.
