TTMS Declares Start Of 2022 Wet Season /

The Trinidad and To­ba­go Me­te­o­ro­log­i­cal Ser­vice (TTMS) is of­fi­cial­ly de­clar­ing the start of the 2022 Wet Sea­son for Trinidad and To­ba­go.

Ac­cord­ing to the TTMS, the of­fi­cial start to the wet sea­son is trig­gered by mea­sur­able rain­fall pro­duced by a Trop­i­cal Wave or the In­tertrop­i­cal Con­ver­gence Zone (ITCZ). Cli­ma­to­log­i­cal­ly, Trinidad and To­ba­go’s Wet Sea­son can ex­tend in­to De­cem­ber be­fore com­plete­ly tran­si­tion­ing in­to the Dry Sea­son in Jan­u­ary.

The Met Of­fice said the Trop­i­cal Wave that trig­gered the start of the 2022 Wet Sea­son moved across the coun­try on Sun­day, May 15th, 2022, in­to Mon­day, May 16th, 2022, and pro­duced rain­fall over sev­er­al ar­eas. They added that while this was the fourth Trop­i­cal Wave the TTMS tracked that moved off the west coast of Africa and tra­versed the Trop­i­cal At­lantic, it is the first one to af­fect Trinidad and To­ba­go.

As of 8 AM on Mon­day, May yield­ed rain­fall to­tals of 28.5 mil­lime­ters which amount­ed to 23 per­cent of May’s av­er­age to­tal rain­fall of 124 mil­lime­ters. The TTMS says the re­main­der of May is like­ly to con­tin­ue with be­low-av­er­age rain across most ar­eas.

While the Wet Sea­son has be­gun, the Met Of­fice says, «At this time, there are no Trop­i­cal Waves over the Trop­i­cal At­lantic, so no wave ac­tiv­i­ty is ex­pect­ed for at least the next week or so. Cur­rent­ly, the ITCZ re­mains south of lat­i­tude 5˚N, but is ex­pect­ed to grad­u­al­ly mi­grate north­ward as the month pro­gress­es.»

The TTMS ad­vis­es, «With the cur­rent La Niña phase, this means fa­vor­able con­di­tions for in­creased cloudi­ness and rain­fall. How­ev­er, the on­go­ing La Niña has in­flu­enced the lo­cal cli­mate in an un­usu­al way, but there is like­ly to be a slow build-up to the wet sea­son rain­fall.»

High Wind Alert Dis­con­tin­ued

With the pas­sage of this first Trop­i­cal Wave, a surge of winds was ex­pect­ed to fol­low overnight Sun­day in­to Mon­day, prompt­ing the Met Of­fice to is­sue a High Wind Alert for both is­lands. Strong winds in ex­cess of 55 KM/H were pos­si­ble, but the high­est wind gust record­ed was 45 KM/H at Pi­ar­co at 3:00 PM, be­fore the High Wind Alert pe­ri­od. The high­est sus­tained winds at Pi­ar­co was 34.5 KM/H, while at Crown Point, it was 33.7 KM/H.

On Mon­day at 10:00 AM, the High Wind Alert was dis­con­tin­ued. Ac­cord­ing to the TTMS, «The threat of wind gusts in ex­cess of 55 KM/H has di­min­ished. Few show­ers and oc­ca­sion­al breezy pe­ri­ods can still be ex­pect­ed to­day. Sea con­di­tions re­main mod­er­ate, with waves in open wa­ters up to 2.5 me­tres and less than 1.0 me­tre in shel­tered ar­eas. Spring tides are al­so in ef­fect.»
