DISCUSSION AND OUTLOOK ---------------------- At 100 AM CDT (0600 UTC), radar data from Belize indicated that the low pressure system was centered near latitude 18.4 North, longitude 87.1 West. The low has been meandering just off the coast of the Yucatan Peninsula during the past few hours, but its longer-term motion is toward the northwest near 5 mph (7 km/h). The low is expected to turn northward later today, with that motion continuing for the next couple of days. On the forecast track, the low or the tropical cyclone should move across the Yucatan Channel near the eastern coast of the Yucatan Peninsula through tonight, and then move into the southern Gulf of Mexico on Monday. Satellite-derived wind data indicate that the maximum sustained winds have increased to near 35 mph (55 km/h) with higher gusts. Additional strengthening is forecast during the next couple of days. The low is expected to become a tropical depression later today and a tropical storm by tonight. A reconnaissance plane will investigate the system this afternoon. * Formation chance through 48 hours...high...near 100 percent. * Formation chance through 5 days...high...near 100 percent. The estimated minimum central pressure is 1004 mb (29.65 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected to first reach the coast within the warning area by tonight, making outside preparations difficult or dangerous. Tropical storm conditions are possible in the watch area tonight and on Monday. RAINFALL: The low is expected to produce total rain accumulations of 3 to 7 inches over western Cuba and 2 to 4 inches over the Yucatan Peninsula, Belize, and northern Honduras through Tuesday. Isolated maximum amounts of 12 inches are possible in western Cuba. A separate area of persistent very heavy rainfall is expected along the Pacific coast of Central America and Mexico, including western Nicaragua, El Salvador, Guatemala, and the state of Chiapas in Mexico. In many of these areas this rainfall could lead to life-threatening flash floods. NEXT ADVISORY ------------- Next complete advisory at 400 AM CDT. $$ Forecaster Berg
