A flood watch is in effect from 1 p.m. today through Sunday.

Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Creeks and streams are running high and may rise out of their banks and could flood with more heavy rain. Flooding may also occur in poor drainage and urban areas.

A low pressure system will bring rain, heavy at times, this afternoon through tonight. Another 1 to 2 inches of rainfall is forecast within the flood watch area in addition to the multiple rounds of rainfall we’ve already had over the past week.

Windy conditions may cause isolated instances of tree damage and power outages on Sunday and Monday.
