Morning Sun and Afternoon Storms, Watching Hurricane Erin

Aug 17, 2025

Sunday features plenty of hot sun in the morning on the mainland, but showers and storms will move in during the afternoon and wind down in the evening. Look for lots of sun in the Keys. Highs on Sunday will be mostly in the low 90s, with a few suburban locations reaching the mid 90s — but it will feel about 10 degrees hotter everywhere, so stay hydrated and out of the sun.

Monday will bring lots of hot sun with afternoon showers and storms developing in the afternoon on the mainland. Monday’s highs will be mostly in the low 90s.

Tuesday will feature a mix of sun, showers, and storms on the mainland. Look for plenty of clouds and periods of showers in the Keys. Tuesday’s highs will be in the low 90s.

Wednesday will see hot sun and clouds alternating with showers and storms on the mainland. Clouds and showers will linger in the Keys. Wednesday’s highs will be mostly in the mid-90s in the East Coast metro area and in the low 90s along the Gulf coast and in the Keys.

Thursday’s forecast calls for a mix of hot sun, showers, and storms on the mainland and mostly sunny skies in the Keys. Highs on Thursday will be mostly in the mid-90s on the mainland and the low 90s in the Keys.

In the tropics, Erin is a powerful major hurricane as it makes its closest approach to the northern Puerto Rican coast. On Saturday evening, Hurricane Erin was about 160 miles northwest of Anguilla and 150 miles northeast of San Juan, Puerto Rico. Erin was moving west at 15 miles per hour at that time. Hurricane Hunter aircraft measured maximum winds of 150 miles per hour — but this is probably because Erin is undergoing an eyewall replacement cycle (quite common in extremely strong hurricanes) and not a weakening trend..

Tropical storm watches are in effect for St. Martin and St. Barthelemy, Sint Maarten and the Turks and Caicos Islands. We’ll continue to watch Erin closely to make sure that it takes the predicted turn to the northwest late in the weekend.

Elsewhere, a weak area of low pressure off the North Carolina coast has a low chance of becoming a depression before Monday, when conditions are expected to be unfavorable for development. And computer models indicate that an area of low pressure could form in the central Atlantic in a few days. This feature has a low chance of becoming a depression during the next week as it moves generally westward — so we’ll keep an eye on it.
