Area Forecast Discussion National Weather Service San Juan PR 441 PM AST Tue Oct 19 2021

SYNOPSIS . Winds will turn more from the east and increase slightly each day till the end of the week. Normal to above normal precipitable water (PWAT) content will continue over the region through at least Thursday. A mid/upper level ridge pattern is expected to promote drier air and more stable conditions aloft late in the week into the weekend.

SHORT TERM. Tonight through Thursday .

Despite slightly lower moisture content than yesterday over Puerto Rico due to the passing of a drier air patch, locally induced afternoon thunderstorms developed across the interior and close to the Luquillo Mountain range by early afternoon. As the afternoon progressed, the activity turned more numerous and, with a low northeasterly steering flow, slowly spread over the southern half of the island. This activity produced ponding of water over roadways and low drainage areas. Additionally, rapid rising rivers were observed especially over Villalba municipality, as rainfalls from recent days caused these areas to react quickly. Additional stream flooding and mudslides over steep terrain cannot be ruled out in the next couple of hours. Normal moisture content over the U.S. Virgin Islands also caused slow passing showers over the local islands with some measurable rainfall accumulations today. The activity over southern Puerto Rico is expected to move away or dissipate around sunset. Showers will affect the northern coastal areas and eastern half of Puerto Rico and the U.S. Virgin Islands at times tonight and early morning hours.

From Wednesday through Thursday, expect ridging aloft to get weaker increasing slightly instability at upper-levels. Moreover, additional moisture will persist as a couple of tropical waves stream across the area one on Wednesday and another one on Thursday. Winds will turn more out of the east southeast tomorrow through Thursday and gradually increase in speed with low-level steering winds reaching close to 15 mph. A frontal boundary will stall northwest of the area through Thursday increasing the moisture convergence effect over the CWA. Some cloud coverage from the tropical waves could inhibit somewhat the diurnal heating effect on afternoon convection. However, although weaker, the ridging aloft could hinder somewhat upper-level cloud formation. Nevertheless, expect somewhat unstable and wet pattern with enough tropical moisture being advected across the area. Therefore, the formation of showers and thunderstorms are likely, especially during the afternoon hours. With the wind shift, a change in affected areas can be anticipated with the bulk of the convective activity in the afternoon focused across the northern half of Puerto Rico, including the greater San Juan and Bayamon Metropolitan area, and at night and morning hours, across eastern half of Puerto Rico and local islands. Although shower and thunderstorm activity will move quicker than in recent days due to faster winds, saturated soils and elevated river levels from past activity will be prone to small stream flooding and mudslides in steep terrain. Any prolonged heavy rain could also trigger urban flooding.

LONG TERM. Friday through Tuesday .

PREV DISCUSSION. /issued 505 AM AST Tue Oct 19 2021/

A drying trend is expected during the long term period, as drier mid-level air filters from the east on Friday and lingers through early next week. This is in response to a building mid to upper level ridge over the northeastern Caribbean. A weak Saharan Air Layer is expected to reach the area during this period. In addition, more stable conditions are expected, due to warmer 500 mb temperatures. This should inhibit widespread convective development across the islands, and decrease the potential for thunderstorm development. At the surface, a broad ridge across the central Atlantic should promote moderate to locally fresh trades, with a tropical wave currently forecast to pass well south of the area on Sunday, having little to no impact in moisture content across the local area. Another tropical wave, with better moisture content may reach the area on Tuesday.

Having said that, expect showers to develop in a diurnal pattern over western PR each afternoon, and across the USVI and eastern sections of PR during the overnight/early morning hours due to passing trade wind showers with mostly light rainfall amounts. Brief isolated thunderstorms could form in the afternoon hours as the trade wind cap is not forecast to be strong enough at this moment.

Mainly VFR conditions will prevail through the forecast period. JPS can expect VCTS/VCSH thru 19/22z. TSRA will develop across the Cordillera Central producing frequent lightning and mountain obscuration, but should remain at a safe distance from JSJ/JBQ. The USVI will possibly observe a few -SHRA/SHRA but mainly VCSH. Winds will remain light and VRB but with sea breeze variations, and gusty in/near TSRA. Winds will return from the NE around 10 kt aft 20/13z.

MARINE . Winds and seas are forecast to gradually increase starting Wednesday onwards, and long period northerly swell is forecast to move across the Atlantic waters and passages by late Friday into Saturday. The combination of wind driven seas and the swell will cause choppy seas up to 6 feet and a high risk of rip currents along the northern beaches of the islands through the weekend.
