?Secure your home: Cover all of your home’s windows. Permanent storm shutters offer the best protection for windows.
?Fill your car with petrol and check your battery, water and oil.
?Check your flashlights, candles and lamps (have spare batteries, bulbs and matches).
?Listen to your Radio and TV constantly for weather reports.
?Locate your containers for storing water for drinking and other uses and label them.
?Pack an emergency survival kit; as shown on the previous page.
?Make sure you have an adequate supply of any prescription medication you may be using.
?Organize your family. Ensure everyone knows the plan.
?Secure canned and non-perishable food.
?Make arrangements to have your pets cared for. If you plan to evacuate.

DISCUSSION AND OUTLOOK
At 1100 AM , the center of Tropical Storm Isaac was located near latitude 14.6 North, longitude 49.7 West. Isaac is moving toward the west near 16 mph (26 km/h) and this motion is expected to continue for the next few days. On the forecast track Isaac is anticipated to move near or over the central Lesser Antilles on Thursday and move into the eastern Caribbean Sea
Maximum sustained winds remain near 70 mph (110 km/h) with higher gusts. Isaac is expected to be near hurricane strength when it moves through the central Lesser Antilles, with some weakening forecast afterward on Friday.
Tropical-storm-force winds extend outward up to 105 miles (165 km) from the center.
The estimated minimum central pressure is 996 mb (29.42 inches).
HAZARDS AFFECTING LAND
RAINFALL: Isaac is expected to produce total rainfall accumulations of 3 to 5 inches with isolated amounts near 10 inches across the southern Leeward Islands late this week, with 1 to 2 inches anticipated across portions of the Windward Islands.
STORM SURGE: A storm surge of 2 to 4 feet above normal tide levels is possible near and to the north of where the center moves through the Lesser Antilles. Near the coast, the surge will be accompanied by large and destructive waves.
WIND: Hurricane conditions are possible within the hurricane watch area by Thursday morning, with tropical storm conditions possible early Thursday in both the hurricane and tropical storm watch areas.
SURF: Swells generated by Isaac will begin to affect portions of the Lesser Antilles on Wednesday afternoon. These swells are likely to cause life-threatening surf and rip current conditions. Continue reading
