Synopsis for puerto rico and the uS. Virgin islands waters... A broad surface trough will continue to hold across the area over the next several days, and this trough will maintain north to northwest winds over the area. Tropical storm sebastien will stay well to our east and north over the next few days. The northerly swell is diminishing across local atlantic waters, with hazardous marine conditions no longer expected, though small craft should continue to exercise caution. Another swell is forecast to arrive Thursday night, and is likely to bring a return of hazardous seas, possibly lasting into the weekend.

SYNOPSIS Active weather will continue today and for the next few days.

Light steering winds and the potential for locally heavy rainfall and thunderstorms bring a persisting risk of localized urban and small stream flooding, especially in areas that have already seen copious quantities of rain over the last several days. The northerly winds expected today into the latter half of the week will see decreasing temperatures over the local islands. In the local waters, another northeasterly swell is forecast to arrive tomorrow night.

SHORT TERM Today through Friday...

Light northerly steering winds will prevail today as the region remains under the influence of Tropical Storm Sebastien located a few hundred miles northeast of the Leeward Islands and a trough north of Hispaniola. This wind flow will bring shallow moisture and passing showers with minor rainfall accumulations over portions of the USVI and the northern sections of PR through the day. Sea breeze variations along the southern coast will aid in the development of afternoon convection along the Cordillera Central and the southern slopes of PR. Soils across some areas are saturated from previous days rainfall and any heavy shower today could lead to urban and small stream flooding.

Although moisture content is forecast to gradually decrease during the next few days, the 500mb temp is forecast to reach -7 degrees C as an upper level trough moves from the west later on Thursday and on Friday. Meanwhile a ridge is expected to build over the western Atlantic and into the local area by the end of the short term period. This will increase the trade winds and bring the remnants of an old frontal boundary across the region. Brisk northeasterly trades and an advective pattern should bring down by a few degrees the MAX temps on Friday.

LONG TERM Saturday through Thursday...

On Saturday, a large ridge to our northwest will act to inhibit the amount of moisture that makes its way over the area from a weak broad trough that is forecast to be to the southeast. Aloft, a cutoff upper-level low is anticipated over the western Caribbean; this will likely keep the environment somewhat favorable for convection. Sufficient moisture is anticipated at low levels to aid in the development of showers and isolated thunderstorms due to local effects and diurnal heating, especially in western, southwestern and interior Puerto Rico, though showers remain possible elsewhere.

On Sunday, the winds are forecast to become more east- northeasterly, and patches of moisture embedded in the trade winds will begin to filter into the region, and will continue to do so through Monday. The upper-level low to our southwest is expected to weaken, leaving a lingering weak trough to the west of the local islands. This trough will make its way across the area Monday as it continues to weaken, and there will be decreasing favorability for convection. Passing showers are possible over local waters and windward portions of the islands during the overnight and morning hours both days. Sunday afternoon, showers are expected, with the peak activity over western and interior Puerto Rico, and a risk of isolated thunderstorms. Showers are expected again on Monday, with the most-affected area being northwestern and interior Puerto Rico as winds shift to out of the southeast.

Tuesday will bring increased moisture to the area as a weak disturbance passes by the forecast area to the south. At the same time, a small upper-level trough is expected to be near Hispaniola. These features will serve to enhance afternoon shower and convective activity. Showers and isolated thunderstorms due to local effects and diurnal heating are most likely over northwestern and interior Puerto Rico, though other areas will still see showers, especially downwind of major orographic features, such as the major islands east of mainland Puerto Rico, and El Yunque. This enhanced shower and thunderstorm activity may be relatively short-lived, as the upper-level trough progresses eastward over the local islands, decreasing support aloft for convection, while, at the same time moisture levels decrease for Wednesday. Patches of moisture, generally in the lower levels of the atmosphere, will continue to stream into the area on the trade winds Wednesday and Thursday. Winds are expected to shift to out of the northeast during this time as well. Passing showers are possible during the overnight and morning hours both days over the local waters, with some pushing onshore in windward areas of the local islands. During the afternoons, thunderstorms again seem less likely; but, showers are still likely due to local effects and diurnal heating, especially in western and interior Puerto Rico.

AVIATION MainlyVFR conditions are expected to prevail across all terminals through the forecast period. However, MVFR to brief IFR conditions are possible between 16z-22z at TJMZ TJPS due to TSRA SHRA. Light winds with a northerly component are expected to prevail with sea breeze variations after 14z.

MARINE Marine conditions are improving in the offshore Atlantic waters, as the swell from yesterday subsides. Seas are expected to be around 4 to 6 feet in Atlantic waters today, and up to 3 to 5 feet in the Caribbean. Another northeasterly swell is expected to arrive overnight tomorrow night or early on Friday morning; hazardous marine conditions are currently forecast for local Atlantic waters associated with this swell, lasting through the weekend. There remains a moderate to high rip current risk at northern beaches of Puerto Rico today, with a low to moderate risk at the beaches of the U.S. Virgin Islands and Culebra.
