A FLASH-FLOOD WATCH IS IN EFFECT FOR ST VINCENT AND THE GRENADINES
Issued at 10:00 am, Saturday 19th August, 2023
An area of low pressure/disturbance with some disorganized showers and thunderstorms now has low-medium chance (20 – 40%) of development and could result in very unstable conditions across St. Vincent and the Grenadines (SVG) today, continuing tonight and during Sunday. Upper-level conditions could enhance pockets of moderate-heavy showers, thunderstorm activity and periods of light-moderate rain with significant rainfall accumulations across SVG possibly near/exceed 100mm (4 inches) within the next 48 hours. As a result, a Flash Flood watch is being issued for St. Vincent and the Grenadines until Monday 21st August 2023 at 6 am…Residents and motorists in areas prone to flooding and landslides or near rivers and streams should be prepared…
A Flood-Watch is issued when conditions are favourable and there exists the possibility of flooding during the watch period. This flash-flood watch may be upgraded to a warning if conditions warrant.
In addition, moderate-fresh (25 – 35km/h) north-easterly trade-winds are expected to turn east south-easterly this evening and southerly during tonight, with occasional gusty/squally conditions (~55km/h). This could result in deterioration of sea conditions this evening, with possible surges near 3.5m - 4.0m on northern and eastern coasts of St. Vincent during tonight, especially around high-tide time 8:02pm…Be prepared to take action!
