A Flash Flood Watch means that moderate to major flooding is possible but not imminent in the watch area.

“Flash flooding is a very dangerous situation,” DDM stated, adding that residents in low lying and flood-prone areas should make preparations for flooding to safeguard life and property.

“They should be prepared to move to higher ground if flooding rains develop or a Flash Flood Warning is issued.”

4 inches of rain in last 12 hours

DDM said an area of disturbed weather in combination with a southeasterly wind flow, aided by a moist environment and critical upper-level support, favours the formation of moderate to heavy precipitation over the Leewards and the VI later today and into tonight.

“Already, up to 4 inches of rain have fallen in some places in the last 12 hours and another 3 or more inches is possible in the next 24 hours. Residents are advised that the watch could be upgraded to warning at short notice,” DDM stated.
