Black Immigrant Daily News

UPDATE: 9am, Thursday, August 25, 2022

This alert message is valid from 9:00 am and will be terminated at 6 pm on Thursday, August 25, 2022, or sooner if conditions warrant.

A flash-flood warning is issued when rapid flooding due to heavy or excessive rainfall in a short period of time (generally less than 6 hours) is occurring or is imminent in the warning area.

**** Hazard Info ****

A tropical wave continues to affect the island, however convective activity associated with this feature has diminished over Barbados resulting in mostly sunny conditions this morning. Lingering instability coupled with light winds and an abundance of atmospheric moisture will result in a high probability of localized activity across northern and northwestern districts.

This activity is forecast to generate cloudy to overcast skies, moderated to heavy showers and thunderstorms over St. Lucy, St. Peter, St. James, sections of St, Andrew and St. Thomas during the late morning into the afternoon. Rainfall accumulations of one (1) to two (2) inches are forecast across the above-mentioned sections of the island during heavy showers. Conditions across the remainder of the island are expected to remain generally sunny and therefore the previously issued flash-flood warning has been discontinued.

UPDATE: 6:30 am, Thursday, August 25, 2022
