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.
