Tropical Depression 20 is becoming better organized and bearing down on
the Yucatan Peninsula.
At 2:00 p.m. EDT Saturday, Tropical Depression 20 was located at 19.3 north, 85.8 west, about 110 miles southeast of Cozumel, Mexico. The depression is nearly stationary. A tropical storm warning is in effect for the eastern coast of the Yucatan Peninsula from Punta Gruesa to Cabo Catoche. A tropical storm watch is in effect for the northwestern coast of the Yucatan Peninsula from Cabo Catoche westward to Campeche. Maximum sustained winds are about 35 mph, and the estimated minimum pressure remains at 1007 millibars, or 29.74 inches. The Hurricane Hunters recently arrived in the storm, and have found winds of about 30 mph so far.
The depression will track over the northern Yucatan Peninsula Saturday night, perhaps briefly reaching tropical storm intensity before landfall. It will then move into the open waters of the southwestern Gulf of Mexico Sunday. After that, the storm should gradually intensify as it tracks westward toward northeastern Mexico, and it could become a hurricane before making landfall. The potential is there for the track to be far enough north to impact southern Texas, and for it to be far enough south that southern Texas remains untouched. All those with interests in the Yucatan Peninsula should be rushing storm preparations to completion, and those along the southern Texas and northeastern Mexican coastlines should monitor the progress of this storm carefully.
As of 11:00 a.m. Saturday, Tropical Depression 19 was located near 14.1 north and 33.8 west, or about 665 miles west of the Cape Verde Islands. Tropical Depression 19 was moving toward the north-northwest at 7 mph with maximum sustained winds of 35 mph and an estimated central pressure of 1008 millibars, or 29.77 inches. TD 19 should slowly track north and could become a tropical storm within the next 24 hours. This feature should generally track to the north-northwest toward the open waters of the Atlantic over the weekend.
The first of the two depressions to reach storm intensity will be named Stan, the second Tammy; either depression could reach tropical storm strength by late Saturday afternoon.
A tropical wave along 74 west, south of 24 north, shows little sign of development. Another wave located near 20 west, south of 20 north, will have to be watched for possible development. An upper-level trough of low pressure interacting with a tropical wave to the northeast of Puerto Rico will have to be watched for slow development over the weekend. This feature could be destined for the Southeast coast of the United States next Tuesday or Wednesday. Another area of disturbed weather southwest of Bermuda will shift west and could bring rich moisture to the Southeast coast early next week.
