Rainfall is expected to be between 40 millimetres (mm) and 80mm today and Friday, and in excess of 100mm on Thursday. The period of normal high tide is expected from Wednesday through to Friday.

All regions are likely to experience cloudy to overcast skies. The highest rainfall is expected to occur over Regions Two to Five. Regions One to Six can expect these conditions coupled with mostly light to moderate continuous rain and showers with downpours which may become heavy at times. Rainfall is expected to be less intense over all other locations.

Coastal areas may experience prolonged water accumulation/flooding in poorly drained, low-lying and riverine areas. The Hydrometeorological Service has been forecasting for the last four days these weather conditions coupled with the high tides.

The Hydrometeorological Service pointed out that this weather forecast, which will see continuous rainfall in the next four days, is on account of the development of an upper–level trough and a subtropical jet stream.

Jet streams are caused by a combination of a planet’s rotation on its axis and atmospheric heating which results in fast-flowing, narrow air currents found in the atmosphere. A subtropical jet stream is the zone of strong winds situated in the upper equatorward side.
