As of 5:00 PM, Hurricane Isaias was located 195 miles south-southeast of Nassau with maximum sustained winds of 75 MPH and a minimum central pressure of 991 mb.
Isaias is moving toward the northwest near 15 MPH, and a general northwestward motion with some decrease in forward speed is expected for the next day or so. On the forecast track,
the center of Isaias is forecast to be near the east coast of the Florida peninsula Saturday afternoon through Sunday.
Strengthening is expected later tonight and early Saturday, and Isaias is forecast to remain a hurricane for the next couple of days before weakening below hurricane strength due
to the combination of strong southwesterly vertical wind shear and interaction with the Florida peninsula.
At this time, there is a great deal of uncertainty in both the track of the storm and how quickly it may move up the coast. Impacts will depend on Isaias’ actual track and intensity
as it approaches New England, but may include high winds of 40 MPH or greater, heavy rain and localized flooding, and storm surge. Typically, the heaviest rain occurs to the west of the storm track and the strongest winds and storm surge occur to the east
of the storm track.
Tropical Storm Force Wind Probabilities (through 2:00 PM 8/05):
Watches, Warnings, Advisories (as of 5:00 PM 7/31)
There are no active watches, warnings, or advisories for Massachusetts. Watches or warnings would be issued
approximately 36 hours before the expected onset of impacts from Isaias.
