The Na­tion­al Hur­ri­cane Cen­ter was mon­i­tor­ing Trop­i­cal Storm Do­ri­an, just un­der 800 kilo­me­tres east of To­ba­go. On its present fore­cast track, this trop­i­cal storm is fore­cast to re­main north of Trinidad and To­ba­go, mov­ing across the Wind­ward is­lands late to­day in­to to­mor­row.

A trop­i­cal storm warn­ing is in ef­fect for Bar­ba­dos as of yes­ter­day af­ter­noon, as trop­i­cal-storm-force winds are ex­pect­ed in 36 hours or less. Trop­i­cal storm warn­ings are al­so in ef­fect for St Lu­cia and the St Vin­cent and the Grenadines, as trop­i­cal-storm-force winds are pos­si­ble with­in 48 hours. There are al­so trop­i­cal storm watch­es in ef­fect for St Vin­cent and the Grenadines and Mar­tinique.

For Bar­ba­dos, St Lu­cia and the St Vin­cent and the Grenadines, trop­i­cal-storm-force sus­tained winds and gusts and pe­ri­ods of show­ers and thun­der­storms are fore­cast to bring pos­si­ble street and flash flood­ing, land­slides and wind dam­age to the re­gion. 25 to 100 mil­lime­tres of rain­fall is pos­si­ble across the re­gion with iso­lat­ed to­tals up to 150 mil­lime­tres.

Coastal flood­ing is al­so pos­si­ble due to storm surge and large waves be­tween 2.5 and 3.5 me­tres in open wa­ters for Bar­ba­dos, St Vin­cent and the Grenadines as well as St Lu­cia. King tides are fore­cast to oc­cur dur­ing this up­com­ing week, which re­sults in high­er than usu­al high tides and low­er than usu­al low tides.

This may re­sult in con­tin­u­ing coastal flood­ing fol­low­ing the pas­sage of Do­ri­an lat­er this up­com­ing week. For Trinidad, To­ba­go and Grena­da, as of 2pm yes­ter­day, no alerts were in ef­fect for these is­lands. How­ev­er, pe­riph­ery ef­fects such as “feed­er band” ac­tiv­i­ty are pos­si­ble, par­tic­u­lar­ly late this morn­ing through ear­ly Wednes­day.

Pe­ri­ods of show­ers and thun­der­storms may in­ter­rupt most­ly sun­ny to part­ly cloudy skies across T&T. Street and flash flood­ing, gusty winds and land­slides may oc­cur in the vicin­i­ty of heavy show­ers and thun­der­storms. Mod­er­ate seas are al­so fore­cast for the north­ern and east­ern coastal wa­ters of T&T. There were no watch­es or alerts for Trinidad and To­ba­go up to late yes­ter­day evening. Al­ready LI­AT has can­celled 15 flights. Af­fect­ed pas­sen­gers have been asked to re­book by Au­gust 28th.
