    Special Weather Statement - 2:47pm Thu Oct 29 2026

    ...ELEVATED RISK OF FIRE SPREAD 11 AM TO 6 PM FRIDAY...

    The combination of dry fuels, gusty northwest winds up to 25 to 35
    mph, and minimum relative humidity values near 40 percent will
    contribute to an elevated risk of fire spread across southern New
    England. The lowest relative humidity and strongest wind gusts
    are expected during the late morning to mid afternoon hours on
    Friday.

    Use extra caution if handling any potential ignition sources such
    as machinery or matches, and ensure to properly extinguish or
    dispose of cigarette butts.
