Synopsis for puerto rico and the uS. Virgin islands waters... A surface high pressure over the eastern atlantic will promote an east-southeast moderate to locally fresh wind flow. This will cause choppy marine conditions across some of the local waters. Isolated Thunderstorms are possible off the west coast of puerto rico each afternoon.

Area Forecast Discussion National Weather Service San Juan PR 935 PM AST Mon Jun 14 2021

UPDATE.

Calm weather conditions will persist due to the arrival of a dry air mass. Overnight lows will drop into the mid 70s across lower elevations and near mid 60s in mountains and valleys. This afternoon's forecast did not have changes.

AVIATION. VFR conditions will prevail overnight. Light and variable winds 15/12z, returning from the E at 10 to 15 knots afterward. Afternoon convection will form between 15/17-22z across the interior and west-PR.

MARINE.

Seas are relatively tranquil to slightly choppy. Winds will remain easterly up to around 20 knots. Seas of 5 feet or less are expected across the local waters.

Beachgoers, there is a moderate risk of rip currents for the eastern coast of Culebra, east and south Vieques, for most of St Croix, and the southeast coast and north-facing beaches of Puerto Rico.

PREV DISCUSSION. /issued 404 PM AST Mon Jun 14 2021/

SYNOPSIS . Hazy skies due to Saharan dust is expected through Thursday. A tropical wave is expected to reach the islands by Friday, enhancing shower and thunderstorm activity. Choppy marine conditions are expected to continue for the next several days.

SHORT TERM . Tonight through Wednesday . Limited shower activity developed during the afternoon hours, with satellite data and rain gauges reporting some showers over northwestern Puerto Rico and across the San Juan metro area. Recent satellite-derived precipitable water imagery shows an area of enhanced moisture moving over eastern Puerto Rico and the eastern U.S. Virgin Islands. However, the guidance are only showing limited rainfall accumulation over eastern Puerto Rico through the overnight hours.

A surface high pressure over the eastern Atlantic will continue to generate a east-southeasterly wind flow across the islands, with a low level steering flow around 17-20 knots. At the mid-levels, high pressure also dominates, resulting in a trade wind cap around 8850- 800 mb. Therefore, moisture is expected to be confined to the lower levels of the atmosphere. Additionally, the aerosol models show a Saharan dust air mass over the eastern Caribbean that should affect the islands at least through mid-week, resulting in hazy skies. In summary, all these features should act to inhibit strong rainfall activity over the area, but still, some passing showers will remain possible each day over eastern Puerto Rico and the U.S. Virgin Islands early in the day, and in the afternoon, with the contribution of local effects, across the interior and northwestern Puerto Rico.

In terms of temperatures, under this wind flow, highs should remain above normal, increasing to the low 90s across lower elevations, with heat indices approaching or slightly surpassing the 100 degree mark.

LONG TERM . Thursday through Tuesday . On Thursday morning, the area will be under the influence of a relatively dry airmass ahead of an approaching wave to the east. Meanwhile, an upper-level trough is forecast to be over or just to the east of the region, providing subsidence to the region. As such, generally fair weather is expected for the first part of the day on Thursday. However, moisture is likely to increase as the wave presses closer to the region. Though the bulk of the wave is forecast to remain to the south of the region, enough is likely to make its way over the islands to bring moisture levels at least to the high end of normal, if not above normal. Meanwhile, a mid- level ridge will persist over the region, maintaining conditions aloft that are not particularly favorable for convection. An increase in shower activity is anticipated, though likely not substantially above normal, with the greatest impacts likely to be seen Friday into Saturday morning.

During the day on Saturday, the wave is forecast to exit the region. Though there will remain some patches of moisture that will be carried into the region embedded in the trade winds, most of this moisture will be in the lowest levels, and total moisture content will likely be on the low end of normal, if not below normal, by Sunday morning. A decrease in shower activity is expected, though local effects and diurnal heating will likely still lead to afternoon convection, and a few passing showers also cannot be ruled out during the overnight and morning hours.

There is decent agreement between the model guidance up until this point in the forecast period - late Sunday/early Monday. Beyond this point, there remains some general agreement on the scenario expected; however, timing and exact details become less certain. This is not unexpected, of course, given a week of lead-time, but it is worth noting that the confidence in the forecast quickly falls off around the start of next week.

The expectation is for another easterly wave to approach and enter the region during the early part of next week, bringing a significant increase in moisture, with precipitable water values likely to be above seasonal normals. Additionally, model guidance suggests that an upper-level trough will be nearby the region during this time. There is a decent chance that this feature will be to the west of the region, placing us on the favorable side for convective development. As such, deep layer moisture is likely, and an increase in activity is anticipated. The timing is quite uncertain, and there has been a not-insignificant amount of inter- run variability on this from the GFS, and the agreement just isn't there with the ECMWF, either. Presently, sometime around Monday into Tuesday seems like a reasonable expectation for the timing of the arrival of the wave, as well as for the more favorable conditions aloft. If the forecast scenario proceeds as expected, it is likely that urban and small stream flooding would be an increasing concern during this time period.

AVIATION . A few streams of -SHRA with sct clds have formed WNW of El Yunque and just SSW of TJBQ. Streamers have formed off the USVI and are moving W, with some VCSH to TIST/TISX. Drier air is entering the Leeward Islands attm. TAF sites TJMZ/TJBQ briefly affected till 14/22Z. Sfc winds ESE with sea breeze influences 10-15G23kt, bcmg aft 14/22Z less than 12 kt in land breezes. Isold SHRA ern PR aft 14/22Z. Max winds SW 25-35 kts btwn FL335-435. Aft 15/14Z sea breezes in ESE flow to resume 12-18 kt with gusts to 24kt with isold SHRA in flow.

MARINE . Choppy marine conditions with seas up to 5 feet and winds up to 20 knots are expected to prevail. These conditions are expected to prevail for the next several days, and small craft operators are urged to exercise caution. For tonight, the rip current risk is moderate for the northern, and southern coast of Puerto Rico, as well as for Vieques and Culebra, and for most of St. Croix and southern St. Thomas and St. John in the U.S. Virgin Islands.
