Tropical Storm Rosa Being Born And Powering Up Quickly Seen By NASA
NASA/Goddard Space Flight Center
The seventeenth tropical depression of the eastern Pacific Ocean hurricane season formed early on October 30 and quickly strengthened into Tropical Storm Rosa. Infrared data from NASA's Aqua satellite revealed strong convection in the storm's center, hinting at that intensification.
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.
