Tropical Depression Five intensified into Tropical Storm Dolly during the overnight hours.  An Air Force Reserve Hurricane Hunter reconnaissance aircraft found that the maximum sustained wind speeds around Tropical Depression Five had increased to tropical storm force and the National Hurricane Center upgraded the system to Tropical Storm Dolly.  The plane also found that a new center of circulation had developed farther to the north of the previous center and the government of Mexico extended the Tropical Storm Warning northward to Barra El Mezquital.

At 8:00 a.m. EDT on Tuesday the center of Tropical Storm Dolly was located at latitude 23.0°N and longitude 95.7°W which put it about 145 miles east-southeast of La Pesca, Mexico and about 220 miles south-southeast of Brownsville, Texas.  Dolly was moving toward the west-northwest at 13 m.p.h.  The maximum sustained wind speed was 50 m.p.h. and the minimum surface pressure was 1005 mb.  A Tropical Storm Warning is in effect from Tuxpan to Barra El Mezquital, Mexico.

Dolly is expected to continue to move toward the west-northwest and it could make landfall in northern Mexico later today.  The Sea Surface Temperatures in the western Gulf of Mexico are very warm and some further intensification is likely.   Locally heavy rains are possible after Dolly makes landfall.
