After a mild beginning to the fall season, things are about to get wet. Really, really wet. And, maybe, a bit loud as well.

The National Weather Service is predicting the first storm system will hit late tonight and continue into the morning hours with the possibility of coastal thunderstorms Wednesday afternoon into Thanksgiving morning.

According to the Eureka office’s hydrologic outlook, the region will potentially see “heavy rainfall and strong south winds" Thursday afternoon into Friday, with amount totals of 2 to 4 inches likely.

“River flooding is not expected,” the outlook states. “However, heavy rainfall may cause small streams and low-lying urban areas to flood.”

For burn scar areas in eastern Trinity and Mendocino counties, flash flooding is possible, according to the forecast.
