A flood warning was in effect this morning for the Snake River in the vicinity of Lewiston because of heavy runoff from recent rains combined with snow melt.

A weak ridge of higher air pressure should bring a break in the wet weather on Tuesday, but forecasters said they expect more rain again on Tuesday night and Wednesday.
