A flash flood watch means that conditions may develop that lead to moderate to major flooding in low lying and flood prone areas.

Precautions should be taken to safe guard life and property. Some houses in low lying and flood prone areas may require evacuation. Flash flooding is a very dangerous situation. You should monitor later forecasts and move quickly to higher ground if flash flooding is observed or imminent or if a flash flood warning is issued.

It’s important to note that just one foot of flowing water is enough to sweep vehicles off the road. When encountering flooded roads, be extremely cautious, and if in doubt, make the smart choice, turn around don’t drown, move to higher ground.

As of 2:00p.m. reports from an air force hurricane hunter aircraft indicate that the tropical wave (Invest 99l) located a few hundred miles east of the lesser Antilles has an elongated and poorly defined circulation. In addition, satellite imagery indicates that the associated shower and thunderstorm activity remains disorganised.

Although it is still more likely than not that the system will impact us as no more than tropical disturbance or strong tropical wave, we cannot rule out the disturbance rapidly developing and impacting us a tropical cyclone. Hence, residents are urged to pay close attention to the progress of this weather system until it is out of our area.

The developing disturbance is expected to cause very wet weather across Antigua and Barbuda and the rest of the Leeward Islands Tuesday night through Wednesday, and across the British Virgin Islands Wednesday through Thursday. Rainfall totals of 25 to 75 mm or 1 to 3 inches are possible. Hence, a flash flood watch and/or warning will likely be required for portions of the next 24 to 36 hours.

Heavy thunderstorms are also expected, which could interrupt electricity and related services. Lightning is very dangerous and everyone should stay indoors when this is occurring.

Seas will become hazardous with peak heights on Wednesday of around 2.7 metres or 9 feet. Hence, small craft and sea-bather warnings will go into effect by this afternoon.

The weather is expected to subside by Wednesday night across the Leeward Islands and by Thursday afternoon across the British Virgin Islands.

At this time, no storm-force winds are anticipated.
