Synopsis for puerto rico and the uS. Virgin islands waters... Surface high pressure north of the area will promote moderate to fresh east-northeast winds across the local waters through tonight. This will result in continuing choppy conditions. Seas and winds will gradually subside into the end of the week. Winds will veer to become more east to southeasterly tomorrow. On Thursday into Friday, a northerly swell will push across the local atlantic waters and passages, though seas are forecast to remain below hazardous criteria.

Area Forecast Discussion National Weather Service San Juan PR 502 PM AST Tue Mar 2 2021
SYNOPSIS. Extended periods under the influence of drier air will maintain generally fair and stable weather conditions during the next few days. The occasional patch of moisture will bring isolated to scattered shower activity, but significant rainfall accumulations are not anticipated. By Friday into early next week, an increase in moisture content with a better chance for showers can be expected as an induced surface trough approaches the area. Further weakening of the wind flow is expected during the next few days, with winds favoring a more southeast flow by the latter part of the workweek into the weekend.
SHORT TERM. Tonight through Thursday .
With extended periods of drier air influencing the local weather conditions, a general fair and stable pattern will prevail during the next few days. However, the occasional patch of moisture embedded in the trade winds will bring isolated to scattered shower activity, with highest impact anticipated for portions of eastern Puerto Rico and the US Virgin Islands during the overnight and early morning hours. Afternoon convection, if any, will cluster along the interior and western sections of Puerto Rico, with a slight chance for shower developing downwind from the local islands and Sierra de Luquillo. Since mid to upper level ridging will maintain unfavorable conditions aloft, with a relatively strong trade wind cap around 850 mb, significant rainfall accumulations nor flooding are expected through the period. At the surface, a moderate to locally fresh east- northeast wind flow will continue through tonight. Thereafter, winds will gradually shift more from the east-southeast on Wednesday and from the south-southeast on Thursday as a surface high pressure migrates eastward into the North Atlantic and a cold front approaches the region from the north. Under southeasterly winds, warmer temperatures can be expected, with upper 80s possible across coastal areas by Wednesday and Thursday.
LONG TERM. Friday through Wednesday .
FROM PREV DISCUSSION. /issued 352 AM AST Tue Mar 2 2021/
The mid-level ridge over the region is forecast to weaken by Friday, but it is expected to build and strengthen once again over the central Atlantic. Meanwhile, an amplifying mid to upper level trough over the western Atlantic will extend into the northeastern Caribbean. A surface front is expected to remain well north of the region, while an induced pre-frontal trough is expected to develop just west of the local area, promoting a weak and moist southerly wind flow on Friday and Saturday. Although global models are not as aggressive as last night solutions, precipitable water (PWAT) content is forecast to remain just above climatology around 1.40 inches. Therefore, expect diurnally induced afternoon showers to develop over the interior and northern sections of PR, due to the light steering winds, slow moving showers could lead to minor flooding.
On Sunday, trade winds are forecast to return to around 15-20 kts and overall fair weather conditions are expected with afternoon showers developing over western PR. For early next week, another induced surface trough is forecast to develop over the local area and increase shower development across the islands. PWAT content is expected to continue above climatology at 1.40-1.50 inches through midweek, favoring afternoon shower development over western PR.
AVIATION. VFR conds expected for the next 24 hours. Brief -SHRA may be possible in the vicinity of the local terminals, but no significant hazards are expected. The local winds will be from the E to ENE at 15 to 20 knots with occasional gusts through 02/22Z. The winds will gradually decrease to around 5-10 knots overnight as they become more easterly. However, the local winds will increase once again up to 15 knots after 03/14Z.
MARINE. Although marine conditions have improved, small craft operators are urged to exercise caution across most of the local waters due to seas up to 6 feet and winds up to 20 knots. A northerly swell is forecast to invade the Atlantic waters and local passages by the end of the workweek, but seas are expected to remain below small craft criteria. There is a high risk of rip currents for beaches along the northeastern coast of Puerto Rico, Culebra, and eastern St. Croix through this afternoon, and beaches along the northwest to San Juan and vicinity coast through late tonight.
