SYNOPSIS
A surface high pressure moving towards the eastern Atlantic will continue to promote breezy conditions across the islands. Dry and fair weather conditions will continue to persist until mid-week.
However, an increase in shower frequency is expected from Wednesday onwards due to the arrival of a cold front and its associated frontal boundary. Warmer temperatures are anticipated this week as surface winds prevails from the southeast.
SHORT TERM
Tonight through Wednesday
Mostly clear skies prevailed across the local region today. Few clouds were seen streaming off the islands and over the Cordillera Central. However, little or none precipitation was observed. Warm temperatures were registered today across the islands. The Luis Munoz Marin Int. Airport in San Juan registered a maximum temperature of 91 degrees Fahrenheit, just 3 degrees below the record for today. Overall, temperatures remained in the upper 80s and low 90s across the coastal and urban areas of Puerto Rico and the U.S. Virgin Islands. Heat indices reached the mid 100s in the municipalities of north central Puerto Rico. Winds prevailed from the east southeast from 15 to 20 mph, with higher gusts.
A surface high pressure continues to dominate the local weather promoting fair weather conditions. However, passing showers dragged by the trade winds cannot be ruled out. By Tuesday, as the surface high moves towards the eastern Atlantic winds will veer from the south southeast. Dry and fair weather conditions will persist with warmer-than-normal temperatures, especially across the north central portions of Puerto Rico and portions of St. Croix. Daytime temperatures will remain in the upper 80s to low 90s across the urban and coastal areas of the islands. Heat indices will stay above the 100s across these areas. From Wednesday onwards, an increase in moisture is expected due to the approach of a cold front and its associated frontal boundary. Therefore, expect an increase in the frequency of passing showers during the morning hours, followed by afternoon showers across the central and western portions of Puerto Rico and the U.S. Virgin Islands. Some of this activity could lead to ponding of water on roads and in poor drainage areas.
LONG TERM
Thursday through Monday...
/FROM PREV DISCUSSION
Issued at 434 AM AST Mon Mar 18 2024/
A weak frontal boundary moving southeastward in the western Atlantic will begin to pass through the region on Thursday, causing a backing of the surface winds to more of a northeasterly direction and a noticeable increase of moisture content moving over the islands by Friday morning. This shifting of the winds and increase of precipitable water will bring a wetter pattern with scattered showers across eastern Puerto Rico and the USVI during the morning hours followed by afternoon convection across western Puerto Rico.
On Friday, a surface low begins to develop in the Gulf of Mexico, migrating into the western Atlantic as it moves along the eastern coastline of the US meanwhile displaying nor'easter characteristics.
Eastward of this system a strong surface ridge will direct a moist easterly flow locally through Saturday which will continue the pattern of an abundance of passing showers with afternoon convection, with the heaviest rainfall over western Puerto Rico during the afternoon.
By Sunday the potential nor'easter would of moved into the upper western Atlantic and a Rossby wave trough develops to the southwest, positioning north of the region by Monday morning. The presence of this will cause a veering in the surface winds to a southeasterly direction on Sunday, becoming southerly and variable Monday onward. During this time precipitable water values spike as this long wave pattern brings a moist airmass and unstable conditions over the eastern Caribbean. This may bring a significant increase of rainfall across the islands for multiple areas, however model guidance is subject to change so stay tuned.
AVIATION
(18Z TAFS)
ESE flow is prevailing over the local area with some sea breeze influences and winds of 8-18 kts with hir gusts--the strongest have been nr TJPS so far. Winds will bcm land breezes btwn 18/23-19/12Z then return to today's flow. VFR conds to prevail but brief MVFR expected in NW PR btwn 18/18-21Z and again fm 19/18-21Z, not necessarily at TJBQ terminal. Max winds W 85-95 kts btwn FL400-470.
MARINE
A broad surface high pressure moving into the central and eastern Atlantic will continue to promote moderate to locally fresh trade winds through mid-week, resulting in choppy seas. Winds will slow down by Tuesday and Wednesday, resulting in subsiding seas and calm conditions across the local waters.
BEACH FORECAST
Breezy conditions will continue to promote a moderate rip current risk along the northern beaches of Puerto Rico, Culebra, the northern U.S. Virgin Islands, and St. Croix. The protected waters of west and southern Puerto Rico and Vieques remain under a low risk. The rip current risk is expected to remain moderate until mid-week, when the risk of rip currents becomes low across all the local beaches.
Rip currents are powerful channels of water flowing quickly away from shore, which occur most often at low spots or breaks in the sandbar and in the vicinity of structures such as groins, jetties and piers. Heed the advice of lifeguards, beach patrol flags and signs. If you become caught in a rip current, yell for help.
Remain calm, do not exhaust yourself and stay afloat while waiting for help. If you have to swim out of a rip current, swim parallel to shore and back toward the beach when possible. Do not attempt to swim directly against a rip current as you will tire quickly.
If you do not know how to swim, we advise you to stay out of the ocean.
