Res­i­dents of Trinidad and To­ba­go have been urged to re­main vig­i­lant as Ad­verse Weath­er Alert #3 - Yel­low Lev­el re­mains in ef­fect un­til 10:00 pm on Mon­day. The alert cov­ers both is­lands and sur­round­ing wa­ters.

The Me­te­o­ro­log­i­cal Ser­vice re­ports that show­ers and iso­lat­ed thun­der­storms have been af­fect­ing the coun­try over the last sev­er­al hours, with heavy down­pours and gusty winds re­port­ed in some ar­eas. To­ba­go has ex­pe­ri­enced par­tic­u­lar­ly fre­quent ac­tiv­i­ty.

While the main ax­is of a strong trop­i­cal wave has moved past Trinidad and To­ba­go, trail­ing mois­ture and un­sta­ble at­mos­pher­ic con­di­tions con­tin­ue to main­tain a high chance of in­ter­mit­tent rain­fall. These con­di­tions are ex­pect­ed to per­sist through Mon­day, with pe­ri­ods of set­tled weath­er pos­si­ble but con­di­tions re­main­ing con­ducive to im­pact­ful weath­er events.

Gusty winds ac­com­pa­ny­ing heavy show­ers and thun­der­storms may dis­place loose out­door ob­jects and fur­ther ag­i­tate seas. Heavy rain­fall could re­sult in street and flash flood­ing, lo­cal­ized pond­ing, and may trig­ger land­slides or land­slips, par­tic­u­lar­ly in hill­side or vul­ner­a­ble ar­eas.

The trop­i­cal wave cur­rent­ly has a low, 30 per­cent chance of de­vel­op­ing in­to a trop­i­cal cy­clone over the next two days, as it moves fur­ther away from the area.

The TTMS ad­vis­es res­i­dents to se­cure loose out­door items and re­main cau­tious, par­tic­u­lar­ly mo­torists and those liv­ing in flood- or land­slide-prone ar­eas.

It says up­dates will con­tin­ue to be pro­vid­ed as con­di­tions evolve.
