SYNOPSIS
The surface high pressure over the western Atlantic will continue to promote breezy northeasterly winds through at least midweek.
Drier airmass between a surface low over the north central Atlantic and the surface high should reach the local area under the northeasterly fetch, but moisture content will oscillate between normal to above-normal values. As a consequence, light to moderate showers with isolated thunderstorms cannot be ruled out of the forecast. By mid-week onwards, instability and moisture levels increase once again as a mid to upper level trough lingers over the western Atlantic and lighter east to southeast winds return.
SHORT TERM
Today through Wednesday...
Showers persisted through the early morning hours across portions of northern and eastern PR and across the USVI. The Doppler radar estimated between 1 and 2 inches of rain over Fajardo and Luquillo.
Minimum temperatures were from the mid-to-upper 70s across coastal areas to the mid-60s across the higher elevations. Wind gusts were up to 20-25 mph with the showers.
A strong surface high-pressure moving off the eastern coast of the U.S. will move slowly towards the Central Atlantic during the next few days. This system will bring slightly drier air to the region, but the amount of precipitable water (PWAT) across the Caribbean will still be within typical seasonal values. The surface high will promote breezy conditions with moderate to fresh northeasterly winds through at least Tuesday, then winds will shift from the east to southeast and become light to moderate on Wednesday as the surface high weakens. Therefore, we expect an advective pattern during the nights with cooler air moving over warm waters and bringing showers across portions of the USVI and along the north and eastern half of PR, followed by diurnally induced afternoon convection over portions of the interior and south/southwest PR each day.
Wednesday looks to be the wettest day of the short-term period as an upper-level trough approaches the area from the west and an induced surface trough develops over the northeastern Caribbean. This will enhance shower and thunderstorm development across much of Puerto Rico. Urban and small stream flooding and mudslides in areas of steep terrain are possible.
High temperatures will remain in the mid-to-upper 80s along the coastal and urban areas and in the mid-to-upper 70s along the mountains and valleys. Minimum temperatures will range from the upper 70s to low 80s across coastal areas to the mid-60s in the higher elevations.
LONG TERM
Thursday through Monday...
The inherited forecast remains unchanged. Recent model guidance suggests a mid-to-upper-level trough developing and staying nearly stationary over the west to southwestern Atlantic, at least through the long-term period. From Thursday onwards, expect the winds to become lighter as the surface high pressure north of the area continues to weaken. By Thursday, remnants of an old frontal boundary will reach the island from the northeast and merge with a trough or perturbation over the northeastern Caribbean. This will lead to unstable and wetter weather conditions across Puerto Rico and the U.S. Virgin Islands, with possible flooding impacts and mudslides in areas of steep terrain across Puerto Rico. At this time, Precipitable Water (PW) models suggest values above two standard deviations and, therefore, above the normal climatological levels for this time of the year. We anticipate active afternoons during the long-term period, with possible flooding impacts and mudslides in areas of steep terrain across Puerto Rico. For the USVI, an increase in the frequency of showers and isolated thunderstorms is possible from Thursday onwards.
Heat indices across the lower elevations of the islands could likely range between 102 and 106 degrees on Friday and Saturday before the onset of afternoon convection. Overall, an unstable and wetter pattern is expected to evolve over the long-term.
AVIATION
(06z) TAFS
Although VFR conds should prevail through most of the period, trade wind SHRA may cause brief MVFR cigs at TJSJ/TIST/TISX/TJBQ at times.
Tempo MVFR conds are possible at TJPS btw 29/18-22z due to TSRA. NE winds at 15-20 kt with stronger gusts near 30 kt during the day.
MARINE
A sub tropical high pressure across the western Atlantic will promote moderate to fresh trade winds through at least mid-week. We expect hazardous seas for small craft operators due to confused seas associated with the increasing winds and a northeasterly swell spreading across the local waters.
BEACH FORECAST
Short-period waves and onshore flow along the northern and eastern beaches of the islands will promote a moderate risk of rip currents to continue this afternoon and tonight. A northerly swell arriving tomorrow (Monday) and stronger winds will increase the risk of rip currents and promote life-threatening rip currents through at least late Wednesday. For more information and details about the latest forecast please refer to the Surf Zone Forecast (SRFSJU) and the Coastal Hazard Message product (CFWSJU).
