The National Weather Service has issued a flood watch advisory as rainfall is expected to continue to hit most of Humboldt County today and into tomorrow morning.

With continuous rainfall forecast today through tomorrow morning, rivers are rising, and roads with poor drainage and low-lying areas are also at risk of flooding, according to Kathleen Vontos at the National Weather Service office in Eureka.

This weekend, Humboldt County saw heavy rain with totals of 4 to 6 inches at Cape Mendocino, 3 inches in Eureka and southern Humboldt. The Humboldt Bay area saw 1 to 2 inches. Rainfall is expected to slow down Wednesday before picking up again Thursday. Lighter rain is expected Friday. Vontos said the rain system has a weird pattern so it is hard to pinpoint exactly how much rain will hit the North Coast.

Most rivers will rise to their highest points and recede throughout today and again on Wednesday. Eel River will reach flood stage by tomorrow morning and again on Wednesday. Mad River Beach Road might see some flooding tonight, as the Van Duzen and Mad rivers will reach monitor stage.

Eel River will reach its highest point near 23 feet Wednesday, Vontos said, and surrounding areas will see flooding impacts at Eel River Delta.

The Humboldt County Office of Emergency Services is warning that the western half of the delta may be completely flooded Wednesday and issued a special action advisory to all livestock owners in low-lying areas. “These animals are at risk due to rising river levels, and appropriate action should be considered,” it said in a press release.
