The Tropical Storm Watch for Jamaica has been upgraded to a Tropical Storm Warning, while a Hurricane Watch has also been issued as computer models continue to project a stronger Sandy approaching the island tomorrow.
This means that tropical storm conditions, including possible sustained wind speeds of 34-63 knots or 63-118 km/h (40-74 mph), are expected in 36 hours or less and that hurricane conditions also pose a possible threat to the country within 48 hours.
Over the next 24-36 hours, rainfall is expected to increase significantly over Jamaica to produce over 250 millimeters (10 inches), especially over central and eastern sections of the island. Flash flooding and landslides are likely.
Tropical storm conditions are expected by early tomorrow morning and hurricane conditions later in the day.
