Elevated Fire Risk & Temperature Rollercoaster

Accelerated Snowmelt Expected Through Friday

A spring weather pattern will bring a "rollercoaster" of temperatures to the region between March 20th and 27th. We are tracking two distinct dry cold fronts arriving on Saturday and Wednesday. While temperatures will moderate to near-normal by Thursday, the primary concern is the development of breezy conditions and low humidity accompanying these fronts. Please use caution with any outdoor burning this coming week, as the fire danger will be elevated.

Occasional rain through Friday combined with warm temperatures will accelerate the melt of a primed snowpack. Stream and creek rises are expected. Also, standing water will accumulate on roads and residential properties. Water could potentially infiltrate basements and low-lying outbuildings. Additionally, snow and debris clogging culverts will force water to sheet over roadways, creating unpredictable driving hazards. Action: Take time now to clear snow and ice away from your home's foundation and nearby storm drains. Never drive through flooded or water-covered roadways.
