On the forecast track, the center of the system will move near or just offshore the coasts of northern Nicaragua and northeastern Honduras, including the Bay Islands, today and approach the east coast of the Yucatan Peninsula of Mexico on Saturday. The center is then expected to cross the Yucatan Peninsula Saturday night and move into the south-central Gulf of Mexico on Sunday. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Strengthening is forecast during the next couple of days, and the depression is expected to become a tropical storm later today. The system is forecast to be near or at hurricane strength when it reaches the Yucatan Peninsula of Mexico late Saturday. Some weakening is expected as it traverses the Yucatan Peninsula Saturday night. Afterward, restrengthening is forecast on Sunday as it moves offshore and enters the southern Gulf of Mexico The estimated minimum central pressure is 1007 mb (29.74 inches).

Tropical storm conditions are expected to first reach the coasts of northeastern Honduras and northern Nicaragua within the warning area this morning, making outside preparations difficult or dangerous. These conditions will spread westward along the coast of Honduras within the warning area today. RAINFALL: The depression is expected to produce the following rainfall accumulations through Sunday: Eastern portions of the Mexican states of Quintana Roo and Yucatan: 3 to 6 inches, isolated maximum totals of 10 inches.
