Mid-elevation snows in this region which usually begin to melt at this time are still above normal levels. The main driving factor for flooding will be the rate of snow melt, and whether significant widespread rains fall on snow covered areas. There is substantial show cover in some higher elevations in New England which, combined with higher than normal streamflows and generally moist soils, has created a somewhat elevated potential for flooding in parts of Maine, New Hampshire and Vermont. But severe flooding will require substantial rainfall. At worst, snow melt alone results in only modest flooding in the Northeast.
Northern rivers have sufficient ice depths to pose a threat for possible ice jam flooding.
Southern Ohio River basin. February and March precipitation has moistened soils and elevated river levels in much of the southern portions of the Ohio River valley. Although there is no significant snow present, these moist conditions make much of Kentucky and southern portions of Indiana susceptible to flooding. In the near term, even moderate rains could be of concern, as runoff would rapidly flow into rivers and streams and inundate low areas. Western Washington and Oregon.
