Whatcom County is in for a wet Halloween, and a warm front could increase the risk of flooding on the Nooksack, Skagit and other rivers by midweek, the National Weather Service said Monday, Oct. 29.

Forecasters predict one to two inches of rain in the lowlands, with up to six inches in the Cascades through Wednesday. Those numbers, added to recent rainfall, could cause minor river flooding. Also expect some street flooding in areas where fall leaves clog storm drains.

Trick-or-treaters will need to be prepared for possibly heavy rain. The forecast at this point shows rain throughout Wednesday.

There might be a break in the rain by Friday, but more rain is expected on the weekend.
