Special Weather Statement

Special Weather Statement issued October 29 at 2:47PM EDT by NWS Boston/Norton MA

Oct 29, 2:47 PM → Oct 30, 6:15 PM

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.
