No big changes to the forecast track of Erin. Still expected to be a major hurricane northeast of Puerto Rico this weekend. Most computer models still showing a turn to the north and northeast next week.

TROPICAL STORM ERIN UPDATE
3 PM MONDAY 8-11-2025

The system I’ve been watching for days became Tropical Storm Erin this morning. While it will occasionally battle pockets of dry, stable air, Erin is expected to strengthen over the next five days — likely becoming the season’s first hurricane and possibly a major hurricane with winds near 115 mph by this weekend. The good news: no land impacts are expected in the next 5 days.

Will Erin reach the U.S.? It’s far too soon to say for certain, but the model trends look encouraging. A strong ridge of high pressure to Erin’s north will steer it west to west-northwest through Friday. Then, a dip in the jet stream off the Mid-Atlantic and New England coasts should weaken that ridge and pull Erin north this weekend and early next week.

Most global models and their ensembles keep the storm north of the Caribbean Islands, east of the Bahamas, and well offshore of the East Coast. But models are guidance, not gospel — subtle errors in the forecast tomorrow can lead to huge errors beyond 5–7 days. For example, if the trough is weaker than expected, Erin could be left behind… and then all bets are off. That’s why we cannot write this system off. IF it were to have a direct impact on the Carolinas, it wouldn't be until August 20th or 21st. At the very least, swells will reach the beaches early next week, producing a high rip current risk and bigger surf.

What should you do now? Just keep checking in daily. Erin is 3,500 miles away — we’ve got plenty of time to watch. If I had Grand Strand vacation plans this week or next, I wouldn’t change a thing. In fact, Cindy and I were invited on a short 3-day cruise from Florida to the Bahamas, and we’re still going. You know me…I’ll be tracking the tropics every day!

Temperatures rising into the lower 90s combined with moderate to high levels of humidity will produce heat indices of 105 to 109 degrees for a brief period this afternoon. Isolated to scattered showers and thunderstorms may provide relief to some areas, especially away from the coast. If heat indices are expected to remain above 108 degrees or 2 hours or more, then a Heat Advisory will be issued.
