Special Weather Statement

Special Weather Statement issued October 29 at 3:09PM EDT by NWS Upton NY
Oct 29, 3:09 PM → Oct 30, 6:00 PM
The combination of dry fuels, gusty northwest winds 20 to 30 mph,
and minimum relative humidity values near 40 percent will lead to
an elevated risk of fire spread across southern Connecticut
during the late morning and 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. Any fires that ignite will have the
potential to spread quickly.

This forecast considers meteorological, fuel, and land conditions
and has been developed in coordination with state fire and land
management officials.

prevention, please visit the Connecticut Department of Energy and
