With local rivers already swollen from previous storms, a flood watch is in effect for much of the Monadnock Region this weekend.
Heavy rainfall is expected beginning this evening and lasting through Saturday night, with up to 1.5 inches possible in some areas, according to a notice from the National Weather Service.
That “will lead to rises in rivers and streams, which are already running high,” according to the weather service.
The flood watch covers Cheshire County and most of Hillsborough County, along with several other areas in the southwestern part of the state.
Localized flooding is expected in urban areas and spots with poor drainage, according to the alert.
Keene’s Public Works Department is taking precautionary measures that include inspecting drain basins, bridge crossings and culverts in the city for debris.
The department is also asking for help. Residents who live near a drain basin and notice leaves piled up can use a rake or a shovel to clear the drain, which will help to prevent temporary pooling of water in the streets.
Drain basins are marked by a yellow fish painted on the road about 6 feet away.
