Maximum sustained winds remained around 70 MPH despite some signs of dry air intrusion. It is forecast to make landfall as a Category 1 hurricane somewhere around Georgetown or the Grand Strand.

The westward shift has some small implications for wind and tide forecasts for this evening. Overall expectations for impacts remain on track, though.

Isaias: Wobble wobble wobble

/ at 9:19 AM

At 8am, Isaias — not the most picturesque hurricane one has ever seen, but a hurricane nonetheless — was making its move on Andros Island in the Bahamas. The storm has been struggling with westerly shear and dry air intrusion, which will keep its intensity capped for now. Today is a pivotal day in the evolution of the storm’s track for the next few days, and we’ll all want to keep an eye on it as we begin to prepare for its arrival Monday.

[UPDATED] Tropical update: Isaias could play a role in our weather early next week

/ July 30, 2020 at 10:18 PM

Tropical Storm Isaias was named with the 11PM advisory last night, and it has brought flooding rain to Puerto Rico over the last couple days as it moved nearby and through Hispaniola. This evening, the center of the storm is reforming on the north side of Hispaniola. There was some speculation that the mountainous terrain of the island would potentially seriously disrupt the storm, but this appears to be a case where that didn’t happen. At 8PM this evening, the storm maintained 60 MPH max sustained winds with the minimum central pressure down to 999 millibars.
