Area Forecast Discussion National Weather Service San Juan PR 407 AM AST Fri Aug 14 2020

SYNOPSIS.

Though conditions are generally drying behind yesterday's tropical wave, there is still sufficient moisture to maintain a typical shower pattern for today. Locally heavy rainfall is possible in southwestern and interior Puerto Rico this afternoon, and there is a risk for urban and small stream flooding. Tropical Storm Josephine is still expected to track well to the north of the area over the weekend. The system could help to pull some moisture across the area, though, bringing showers for Saturday.

SHORT TERM. Today through Sunday . For today, a patch of moisture is forecast to move over the local area and cause scattered showers in the morning. Then, isolated to scattered showers are possible due to local effects mainly over portions of eastern into the central interior of Puerto Rico. However, some portions of the western interior into the southwestern quadrant of Puerto Rico may observe numerous showers and isolated thunderstorms this afternoon, some showers could be heavy at times and could cause minor flooding. Another band of moisture will move in tonight, and cause widely scattered showers across the local area, especially the local waters, USVI, and eastern PR. A small area of dry air will then move in on Saturday morning, lingering into the early afternoon hours and causing mainly fair weather. That said, a band of moisture associated with Tropical Storm Josephine will move in on Saturday night, and affect the local waters, northern PR, and northern USVI. But this forecast has a high uncertainty since it is highly dependent on the overall organization and general track of Josephine. However, it is expected for the overall moisture to increase across portions of the local forecast area, likely on the Atlantic side as Josephine passes to the NE of the local islands. The latest model guidance suggests that a dry slot will move in on Sunday, although there again will be some uncertainty. But the GFS model suggests that a slot of dry air will move in on Sunday along with southerly winds. This setup would cause an increase in daytime temps across the northern half of PR, possibly causing temps in the low to mid 90s. That said, if the winds are as light as the models suggest, a strong sea breeze would moderate these temps near the coast, and the higher than normal temps would be more common a few miles inland on the northern side of the island.

LONG TERM. Monday through Saturday .

On Monday, moisture associated with Tropical Storm Josephine combined with a relatively weak wave will stream across the area. As such, an increase in shower activity is anticipated across the region, with afternoon showers and thunderstorms, especially in northwestern Puerto Rico. Behind the wave is a large area of disorganized patches of moisture, which are anticipated to affect the area of Tuesday. Moisture is likely to decrease late in the day, however. A typical pattern is likely on the day, with shower activity becoming more inhibited in the evening. This is due to a small area of dry air ahead of another wave.

Late on Tuesday night, a vigorous tropical wave is forecast to make its way into the area. Significantly higher moisture levels are anticipated, and shower activity is likely to be fairly widespread. The wave will linger over the area into Thursday. Once again, a drier air mass is expected to move in ahead of the next wave mid- morning on Thursday through the afternoon. The next wave is forecast to arrive overnight on Thursday night into Friday, and this one is also expected to be fairly vigorous. Another surge of moisture across the area will lead to an increase in showers. Widespread afternoon showers with isolated thunderstorms are anticipated for Friday, with the peak in activity in western and interior Puerto Rico. This will be followed by enhanced passing shower activity during the night.

On Saturday, disorganized patches of moisture will help to sustain shower activity across the area. Late in the day yet another tropical wave is forecast to approach the area. So, on the whole, next week is currently looking to be fairly repetitive.

AVIATION.

VFR conds expected through the forecast period across the local terminals. VCSH is expected however, and a few brief SHRA may affect the terminals, but it is not expected to significantly reduce VIS or CIGs. TSRA is possible across SW-PR this afternoon, which may cause VCTS at TJPS between 14/16 and 14/21. After 14/13Z, winds will increase to around 15KT, from the east but with sea breeze variations.

MARINE.

Winds of up to 20 knots persist across the bulk of the local waters, contributing to continuing choppy conditions. Seas of up to 6 feet are anticipated for portions of the Atlantic waters, with seas up to 5 feet elsewhere, through the weekend. Tropical Storm Josephine is still forecast to pass by well to the north of the area over the weekend. This has the potential to cause some deteriorating conditions, mostly in the offshore Atlantic waters; though the current forecast keeps waves to around 6 feet at maximum, locally hazardous conditions cannot be ruled out.

There is a moderate risk of rip currents at most northern beaches of Puerto Rico, as well as a handful of beaches in the southeast and southwest, and eastern Culebra and St. Croix.
