[LincolnTalk] Fwd: Situational Awareness Statement: Hurricane Isaias – Forecast and Readiness Actions

Bob Antia

Looks like we could get some rain.


Massachusetts Emergency Management Agency


DATE: July 31, 2020
TIME: 5:00 PM
SUBJECT: Hurricane Isaias – Forecast and Readiness Actions


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):

  • Nantucket: 23%
  • Hyannis: 17%
  • Boston: 12%
  • Worcester: 10%
  • Springfield: 9%


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.

  • The State Emergency Operations Center (SEOC) is currently operating at Level 1 (Steady State Monitoring) but may transition to Level 2 (Partial Activation) on Sunday or Monday, depending on updated forecasts.  MEMA will continue to monitor the progress of Isaias over the weekend and will disseminate an updated Situational Awareness Statement each day around 5:00 PM, with additional spot reports as needed.
