Another Tropical Cyclone Developing Hurricane Season 2012:
Tropical System 92E (Eastern Pacific Ocean) While Tropical storm
Aletta is forecast to weaken and dissipate another tropical
cyclone appears to be forming in the eastern Pacific south of
Acapulco, Mexico. The TRMM satellite passed above this tropical
disturbance (92E) on 18 May 2012 at 0957 UTC. Data captured with
this pass by TRMM's Microwave Imager (TMI) and Precipitation
Radar (PR) instruments were used in the rainfall analysis shown.
This analysis indicates that this area contained very heavy
rainfall in the northeastern quadrant of the disturbance. Some
storms were producing rainfall at a rate of over 50 mm/hr (~2
inches). A 3-D image from TRMM PR shows that a few of these
strong convective storms reached heights of about 15km (~9.3
miles). Radar reflectivity values of over 50 dBz found by TRMM
PR in this stormy area provided more evidence that heavy
rainfall was occurring. The National Hurricane Center (NHC)
assigned this disturbed area a 40% pr
