An ac­tive trop­i­cal wave in the cen­tral trop­i­cal At­lantic is ex­pect­ed to be­gin af­fect­ing the South­ern Wind­ward Is­lands from Thurs­day, but the Trinidad and To­ba­go Me­te­o­ro­log­i­cal Ser­vice (TTMS) says the sys­tem cur­rent­ly has a low chance of de­vel­op­ing in­to a trop­i­cal cy­clone.

In an of­fi­cial state­ment, the TTMS said the wave was cen­tred ap­prox­i­mate­ly 1,900 kilo­me­tres east of the South­ern Wind­ward Is­lands and was mov­ing west­ward at about 28 kilo­me­tres per hour.

The sys­tem re­mains dis­or­gan­ised, with scat­tered ar­eas of show­ers and thun­der­storms. Ac­cord­ing to the Met Ser­vice, there is cur­rent­ly a 10 per cent (low) chance of trop­i­cal cy­clone de­vel­op­ment dur­ing the next two to sev­en days.
