WEDNESDAY’S WEATHER FORECAST: 5/8/24
Happy Wednesday!
According to the National Weather Service (NWS) in San Juan, Puerto Rico, an unstable weather pattern is expected again on Wednesday as a mid to upper-level trough (an area of low pressure) passes across the region. Additionally, there is a lot of tropical moisture around the islands. The ground is saturated, and any additional heavy rainfall could result in flash flooding or mudslides. Therefore, Wednesday will be mostly cloudy, with scattered showers and thunderstorms. Thunderstorms may be severe at times. The high temperature will be approximately 87°F, 30.5°C, with winds out of the east-northeast at about 6 to 8 mph. The chance of rain on Wednesday is approximately 60%.
Wednesday night will be mostly cloudy, with showers and thunderstorms. The low temperature will be approximately 78°F, 25.5°C, with winds out of the east at about 11 to 13 mph. The possibility of rain on Wednesday night is approximately 60%.
A drying trend is forecast later this week as an area of high pressure builds over the Northeast Caribbean.
Below: Infrared satellite imagery obtained at 6:40 p.m. AST on Tuesday indicates a mostly cloudy sky with precipitation around the USVI and Puerto Rico. Additional rainfall and thunderstorms are possible over the next few days.
MARINE WEATHER UPDATE
A northeasterly swell is expected to impact the islands, creating hazardous marine conditions. Also, gusty winds and possible thunderstorms may generate wind-driven, choppy seas.
On Wednesday, the seas will be approximately 2 to 4 feet, with occasional seas up to 5 feet. Winds will be out of the east-northeast at about 5 to 10 knots.
On Wednesday night, the seas will be approximately 3 to 5 feet, with occasional seas up to 6 feet. Winds will be out of the east at about 10 to 15 knots, gusting up to 20 knots.
The water temperature is approximately 83-85°F, approximately 28-29°C.
