Synopsis for puerto rico and the uS. Virgin islands waters - . A surface ridge over the north-central atlantic and broad surface trough across the eastern caribbean will generate moderate to locally fresh east to northeasterly winds through tonight. An upper level trough and induced surface trough will continue to promote inclement weather across the local waters over the next few days, with squally weather and Thunderstorms possible at times. A northeasterly swell is forecast to arrive by tomorrow.

SYNOPSIS
Unstable weather conditions are expected to prevail across the local area through at least today. Showers and isolated thunderstorms are also expected during the overnight hours.
Therefore, there is the potential for minor flooding, river rises and mudslides due to soil saturation. Conditions should improve tomorrow into the weekend, however wet conditions are expected next week. Marine conditions will slowly improving across the local waters, however, a northeasterly swell is forecast to arrive Thursday.
SHORT TERM
Today through Friday...
A broad surface trough extending across the northeast Caribbean and surface high pressure over the southwest Atlantic will maintain light east northeast winds across the area today into Thursday, then forecast to become more easterly by Friday. A mid to upper level trough will continue to slowly shift eastward across the region through Thursday, then linger across the northern Leeward Islands by Friday with another short wave trough forecast to cross the west Atlantic and just north of the region by then. The proximity of the upper trough along with the surface trough and a weak area of low pressure now forecast to develop northeast of the region over the next few days will support a fairly moist and unstable environment through the period.
Recent satellite imagery and doppler weather radar showed mid to high level cloudiness and light to moderate showers accompanying the upper trough just west and north of the region, while fewer showers were noted over the islands and coastal waters steered by the east northeast winds. Shower activity continued to wane over land areas overnight, while rivers and streams slowly subsided. However another round of developing showers is expected to affect the islands later this morning and during the afternoon aided by local and diurnal effects. Early morning low temperatures remained in the mid to upper 70s along the coastal areas and in the upper 60s to low 70s in higher elevations. Winds were calm to light and variable.
Through the rest of the period, unstable weather conditions are forecast to continue, due to the meandering upper trough and good low level moisture convergence. Present model guidance as well as recent satellite derived precipitable water products and analyses all suggest precipitable water values ranging between 1.70-1.85 across the region today. However this is forecast to gradually diminish to between 1.65-1.70 inches by Friday favoring less widespread shower activity and deep convection. The overall scenario still suggests sufficient instability aloft and plenty of moisture available for enhanced of overnight showers and isolated thunderstorms across portions of the islands and local waters during most of the period. Developing showers with periods of locally heavy rains will be possible each day and any additional rains may lead to ponding of water and flooding in flood prone areas as well as quickly reacting rivers and streams along with water surges with flash flooding, and landslides.
LONG TERM
Saturday through Wednesday...
Areas of low pressure spread across the central Atlantic basin and developing surface high in the western Atlantic will maintain moderate NE winds through the weekend along with enough water content in a lingering airmass to allow passing showers and afternoon convection to fire up due to diurnal heating and local effects. By Sunday, an area of lower pressure near Florida will assist the lifting of a moist airmass from the eastern Caribbean, raising precipitable water values well above average values. This in combination with a mid to upper-level trough, with the jet max over the region through late Sunday, will allow an increase of passing showers and afternoon convection mainly across western Puerto Rico.
Winds begin to strengthen and veer, becoming more easterly to southeasterly Monday to Tuesday, respectively, as the aforementioned surface high moves into the central Atlantic. Due to all of this a wet pattern is expected from Sunday onward with Wednesday containing a best chance for widespread rainfall.
