Cli­mate Change Ed­i­tor & Weath­er An­chor

The Trinidad and To­ba­go Me­te­o­ro­log­i­cal Ser­vice (TTMS) has de­clared the of­fi­cial start of the 2025 Wet Sea­son, fol­low­ing rain­fall linked to the In­ter-Trop­i­cal Con­ver­gence Zone (ITCZ).

A Yel­low Lev­el Ad­verse Weath­er Alert was is­sued from Sat­ur­day, May 17, and ex­tend­ed to Mon­day, May 19, af­ter heavy rain and thun­der­storms caused flash flood­ing in parts of Trinidad.

That Alert was dis­con­tin­ued on Mon­day af­ter­noon.

The TTMS not­ed that al­though the ITCZ's main ax­is re­mains south, deep mois­ture in its broad­er en­vi­ron­ment is af­fect­ing T&T.

The El Niño South­ern Os­cil­la­tion cur­rent­ly is neu­tral but could shift to La Niña lat­er in the sea­son, po­ten­tial­ly in­flu­enc­ing rain­fall.

The TTMS al­so con­firmed the first trop­i­cal wave of the year and warned of in­creased Sa­ha­ran dust in June.

The pub­lic is ad­vised to pre­pare for the Wet and Hur­ri­cane Sea­sons.
