The circulation around a low pressure system over the Eastern North Pacific Ocean southwest of Mexico organized quickly during Tuesday and the U.S. National Hurricane Center designated the system as Tropical Storm Adrian. A well defined low level center of circulation developed at the center of the low pressure system. Thunderstorms formed rapidly neat the center of Adrian’s circulation. Many other thunderstorms formed in bands revolving around the center of circulation. Storms near the center of Adrian began to generated upper level divergence that pumped mass away from the tropical storm. Winds to tropical storm force extended out 45 miles (75 km) from the center of Tropical Storm Adrian.

Tropical Storm Adrian will move through an environment very favorable for intensification during the next 36 hours. Adrian will move over water where the Sea Surface Temperatures are near 28˚C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Tropical Storm Adrian will intensify during the next 36 hours. Adrian could intensify rapidly at times. Tropical Storm Adrian could strengthen to a hurricane on Wednesday.

Tropical Storm Adrian will move around the southern side of a high pressure system that extends from Mexico to over the Eastern North Pacific Ocean.
