Tropical Storm Trudy Forms Southeast of Acapulco

A center of circulation formed within a large area of low pressure south of the coast of Mexico and the system has been classified as Tropical Storm Trudy.  At 11:00 p.m. EDT on Friday the center of Tropical Storm Trudy was located at latitude 15.6°N and longitude 99.0°W which put it about 100 miles southeast  of Acapulco, Mexico.  Trudy was moving toward the north at 8 m.p.h.  The maximum sustained wind speed was 40 m.p.h. and the minimum surface pressure was 1005 mb.  The government of Mexico has issued a Tropical Storm Warning for the portion of the coast from Tecpan de Galeana to Laguna de Chacahua.

A high pressure system over the northern Gulf of Mexico is steering Trudy northward and this motion is expected to continue on Saturday.  Trudy is likely to make landfall on the Mexican coast during the next 24 hours.  The greatest risks are from heavy rainfall and flooding.

Trudy is over warm Sea Surface Temperatures and the upper level winds are not strong.  So, the environment is conducive to intensification.  However, the circulation around Trudy will interact with land soon and there is a limited time during which intensification could occur.

There is a possibility that the middle level circulation of Trudy could cross Mexico and interact with a stationary front over the Bay of Campeche to spin up a low pressure system over the southern Gulf of Mexico next week.

Trudy is the first T-named storm to form over the Eastern North Pacific since Tina in 1992.
