The Trinidad and To­ba­go Me­te­o­ro­log­i­cal Ser­vice (TTMS) has is­sued two yel­low-lev­el alerts for ad­verse weath­er and haz­ardous seas, warn­ing that un­sta­ble con­di­tions could con­tin­ue through Mon­day night.

Al­though the ax­is of an ac­tive trop­i­cal wave has moved west of the re­gion, the Met Of­fice said trail­ing mois­ture and in­sta­bil­i­ty are like­ly to pro­duce pock­ets of heavy show­ers and iso­lat­ed thun­der­storms across both is­lands and sur­round­ing wa­ters un­til 10 p.m. Mon­day. It cau­tioned that sat­u­rat­ed soils in­crease the risk of street and flash flood­ing, lo­cal­ized pond­ing and pos­si­ble land­slides along hill­sides and oth­er vul­ner­a­ble ar­eas. Gusty winds are al­so ex­pect­ed near heavy show­ers and could dis­place loose out­door items and ag­i­tate seas.

Sep­a­rate­ly, a haz­ardous seas alert re­mains in ef­fect for north­ern coastal ar­eas of Trinidad and To­ba­go and parts of the Gulf of Paria un­til 3 p.m. Tues­day. The TTMS said high-en­er­gy, long-pe­ri­od norther­ly swells -- with in­ter­vals of up to 16 sec­onds -- com­bined with spring tides could pro­duce larg­er than nor­mal break­ers, bat­ter­ing waves and salt-wa­ter in­tru­sion. The con­di­tions may dis­rupt fish­ing, swim­ming and boat moor­ings, and cause coastal sand dis­place­ment.

Res­i­dents, mo­torists and ma­rine users are urged to ex­er­cise cau­tion, se­cure loose items and re­strict nearshore ac­tiv­i­ties. The TTMS ad­vised con­tin­u­ous mon­i­tor­ing of of­fi­cial up­dates via its web­site and the Of­fice of Dis­as­ter Pre­pared­ness and Man­age­ment.
