SYNOPSIS
An elevated risk of flooding, with thunderstorms is expected for today and Thursday. Conditions will become more seasonal this weekend, but still with enough moisture to generate showers and isolated thunderstorms. Hot conditions will persist each afternoon, with little relief for areas with the lowest cloud coverage.

SHORT TERM
Today through Friday...

Isolated to scattered showers were observed all night into the early morning across some coastal sections of St. Thomas. According to radar estimates, rainfall accumulations were minimal. Several pockets of showers with thunderstorms affected most of the local waters, causing localized higher seas and gusty winds. Due to these conditions, a marine weather statement was issued for most of the local waters. The islands registered minimum temperatures in the upper 70s to lower 80s across the coastal areas and in the mid to upper 70s across the interior sections.

A similar weather pattern will persist today into Thursday across the region. At the surface, the islands will continue to be influenced by the interaction between a broad surface high pressure over the Central Atlantic and an induced surface trough just northwest, resulting in a light southeast wind flow over the region.
This wind flow will continue to bring plenty of tropical moisture, with PWAT values exceeding 2 inches from the previous tropical wave now located over Hispaniola. A similar pattern will prevail in the mid-to-upper levels; a deep trough will continue to increase instability, enhancing colder temperatures at 500 mb and divergence aloft. These conditions will enrich vertical development, and deep afternoon convection is forecast again across the interior sections of the island. According to the Galvez-Davison Index (GDI), a good indicator of thunderstorm activity, there is a good chance to observe scattered thunderstorms with the heaviest activity today.
Since the surface winds remain light, resulting from the relaxation in the pressure gradient, slow-moving showers could result in significant rainfall accumulations. That is why there is an elevated risk of flood threats across most of the CWA today. Residents are urged to check weather conditions for further updates.
The forecast remains on track for Thursday. As the induced surface trough moves westward, building surface high pressure over the North- Central Atlantic will tighten the pressure gradient and create backing winds. This wind flow will continue to drag moisture across the region, resulting in a persistent wet pattern. The prevailing winds will focus the showers more on the interior and western sections. By Friday, the available moisture will diminish, resulting only in localized showers for the afternoon hours.

Due to the significant rainfall observed over the past few days, soils are already saturated, leading to urban and small-stream flooding in some areas across the islands. Therefore, it's crucial for residents and visitors to be aware of these conditions for safety and operational reasons and to check weather conditions during the day for possible advisories or warnings.

LONG TERM
Saturday through Wednesday...

A surface high pressure centered over the eastern Atlantic will drive the trade winds from the east during the weekend, bringing occasional showers across eastern Puerto Rico and the Virgin Islands, and followed by afternoon convection across western Puerto Rico.

Early next week, a mid level ridge will build north of the region, and the surface high pressure will strengthen as it moves westward. At this time, an induced surface trough will approach the area, and a tropical wave will cross the eastern Caribbean. The moisture from these surface features will bring an increase in showers to the area, mainly for the Virgin Islands, local waters and eastern Puerto Rico. Accumulations are not expected to be too significant because the low level steering flow will be enhanced.
Saharan dust will follow on Tuesday, lasting through Wednesday. Then on Wednesday, another trough will dig from the northeast, shifting the winds from this direction. All these days, afternoon convection is anticipated, mainly for the interior and western Puerto Rico. The activity could be strong, with possible lightning, and urban and small stream flooding developing.

The heat risk will be elevated all these days, impacting outdoor activities, and those without effective cooling or poorly hydrated.



AVIATION
(06z)

Briefly, VFR conditions will persist for most of the TAF sites until SHRA and TSRA develop from 19/Z across the islands. These conditions will result in MVFR and brief IFR conditions across the major TAF sites of the island where TSRA ceiling in the FL020 & FL030 are forecasted. Lower ceilings and limited VIS are expected over the mountains as well. Winds will continue light and VRB, increasing at 19/15Z from the E-SE at 12 knots with gusty winds near the showers.

MARINE
Surface high pressure over the Atlantic will promote moderate to locally fresh easterly winds through the rest of the week. Passing showers and isolated thunderstorms accompanying and trailing a tropical wave will continue to affect the coastal waters and local passages resulting in localized hazardous marine conditions.
