Special Weather Statement

Special Weather Statement issued September 30 at 1:41PM EDT by NWS Boston/Norton MA

There is an elevated fire risk on Wednesday, due to combinations of
factors; north-northeast gust up to 20 MPH, relative humidity values
between 35 and 40 percent, and drought-stressed fuel littering the
ground. A period between late-morning and sunset are expected to
bring the lowest RH values and strongest wind gusts.

This forecast takes into account meteorological, fuel, and land
conditions, and was developed in coordination with state fire and
land management officials.

Open burning is not recommended on Wednesday. Follow instructions of
local fire wardens. Be very careful when handling and disposing of
ignition sources outdoors, such as cigarettes or matches.
