None. SUMMARY OF WATCHES AND WARNING IN EFFECT... A Hurricane Watch is in effect for... * Barbados A Hurricane Watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous.

Gonzalo is moving toward the west near 12 mph (19 km/h). A general westward motion at a faster forward speed is expected during the next few days. On the forecast track, the center of Gonzalo would approach the Windward Islands late Friday and Saturday. Maximum sustained winds are near 60 mph (95 km/h) with higher gusts. Strengthening is forecast during the next couple of days, and Gonzalo is expected to become a hurricane on Thursday. Tropical-storm-force winds extend outward up to 35 miles (55 km) from the center. The estimated minimum central pressure is 998 mb (29.47 inches). HAZARDS AFFECTING LAND ---------------------- None.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Watch is in effect for... * Port Mansfield to High Island Texas A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. Interests elsewhere along the Texas and Louisiana coast should monitor the progress of this system. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND OUTLOOK ---------------------- At 100 AM CDT (0600 UTC), the center of Tropical Depression Eight was located near latitude 25.9 North, longitude 88.8 West. The depression is moving toward the west-northwest near 6 mph, and this general motion is expected during the next few days. On the forecast track, the center of the depression is expected to move across the northwestern Gulf of Mexico today and Friday and make landfall along the Texas coast on Saturday. Maximum sustained winds are near 30 mph (45 km/h) with higher gusts. Slow strengthening is expected, and the depression could become a tropical storm in a day or so. The estimated minimum central pressure is 1009 mb (29.80 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are possible within the watch area by late Friday. RAINFALL: The depression is expected to produce 2 to 4 inches of rain with isolated maximum totals of 6 inches along the Gulf coast from Louisiana to the Lower Texas coast, and inland through south-central Texas and the Rio Grande Valley. SURF: Swells generated by the depression are expected to increase and affect much of the Texas and Louisiana coasts in a day or two. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 400 AM CDT. $$ Forecaster Pasch
