“Since spring freshet has not ended in many areas, flooding is possible in the most vulnerable areas,” warns the alert. The term ‘freshet’ is most commonly used to describe a rush of fresh water flowing into specific areas.

“Localized flooding in low-lying areas is possible,” concluded the warning.
