    DATE: 10/29/2020
    TIME: 3:30 PM
    SUBJECT: Post-Tropical Cyclone Zeta – Potential Impacts Tonight/TomorrowHurricane Zeta, now a strong post-tropical cyclone, will bring soaking rain to southern New England through tonight, with strong winds along the coast tonight into Friday. A widespread 1-2 inches of rain with isolated higher amounts will occur over southern New England. Rain will change over to snow late tonight into Friday morning. Snow accumulations of 1-3 inches with isolated higher amounts in higher terrain are possible across Western, Central and interior Northeast Massachusetts.

    The Cape and Islands are forecast to see sustained northeast winds of 20-30 MPH with gusts up to 50 MPH tonight through early Friday afternoon. Gusts of up to 40 MPH are possible elsewhere along the southeast New England coast.

    The storm will move out of the area by Friday afternoon. Weather on Saturday will be dry but chilly, followed by milder conditions Sunday. Dry but colder than normal weather is forecast for early next week.

    Areas of uncertainty with this forecast include:

    • The timing of the changeover from rain to snow tonight and how heavy precipitation may be following the changeover. This will impact final snowfall totals.
    • Whether winds along the southeast New England coast may be stronger than forecast, given Zeta’s intensity when it made landfall.

     Impacts:

    • Gusty winds may cause isolated pockets of tree and wire damage and isolated power outages.
    • Snowfall totals of 3 inches or more could result in isolated pockets of tree and wire damage and isolated power outages. Additionally, snow accumulations may result in hazardous travel conditions during the Friday morning commute.
