A low pressure system over the southern Bay of Campeche has been classified as Tropical Depression Five (TD5).  At 5:00 p.m. EDT on Sunday the center of TD5 was located at latitude 20.1°N and longitude 93.6°W which put it about 255 miles east-southeast of Tuxpan, Mexico and about 465 miles south-southeast of Brownsville, Texas.  TD5 was moving toward the west-northwest at 13 m.p.h.  The maximum sustained wind speed was 30 m.p.h. and the minimum surface pressure was 1009 mb.  A Tropical Storm Warning has been issued for the portion of the coast from Tuxpan to La Pesca, Mexico.

TD5 is expected to move toward the west-northwest and intensify into tropical storm Dolly before it makes landfall.  The circulation of TD5 is interacting with a small upper level low north of the system, which is creating some northwesterly shear over it.  The shear is causing most of the thunderstorms and stronger winds to occur southeast of the center.  The shear will also limit intensification over the short term.  Heavy rain may be possible to the north of the center when the system makes landfall.
