Good morning, St. Croix. It looks like another day of classic Caribbean heat paired with those persistent, breezy trade winds. If you were hoping for a break from the humidity, you might want to keep the AC running or find a nice shaded spot with a cross-breeze.
The Forecast Highlights
The Heat is On: Expect warm-to-hot conditions to dominate the week. Heat indices are projected to climb above 100°F, especially in coastal and urban areas.
Breezy Conditions: A tightened pressure gradient is keeping things moving. Expect east to east-southeast winds between 15-20 mph, with potential gusts reaching up to 30 mph.
Passing Showers: While the morning started with a few wind-driven showers, most of the significant rainfall and isolated thunderstorms this afternoon will stay focused over interior and northwestern Puerto Rico. For the USVI, expect mainly sunny skies with the occasional "liquid sunshine" passing through quickly.
Looking Ahead
Saharan Dust: Keep an eye on the horizon starting Wednesday. A minor concentration of Saharan Air Layer (SAL) dust is expected to arrive, which may lead to hazy skies and slightly reduced air quality through the end of the workweek.
Marine & Surf: Seas are holding at 3 to 5 feet, but conditions remain choppy due to the wind. There is a moderate risk of rip currents for north- and east-facing beaches. If you're heading to the water, stick to protected coves.
Safety Note: With heat indices hitting triple digits, stay hydrated and take frequent breaks if you’re working outdoors. These temperatures are nothing to scoff at—even for those of us used to the tropical sun.
Whether you're managing a local business or planning a move—perhaps looking for a quiet plot of land on the East End to "pick up stakes" and settle down like a billionaire seeking a tax-friendly paradise—today’s weather is a reminder of why we love (and respect) the island climate.
