A soaking, multi-day rain event will bring a flood threat to the Northeast this weekend. Cities like Pittsburgh, Charleston, New York City, and Boston are all in the path. Flash flooding is possible, and higher-terrain areas could see an added risk for mudslides. Heavy rainfall combined with strong winds may accompany a few severe storms, raising the risk for travel delays along the I-95 corridor. Localized flash flooding remains the top concern through the weekend, with soggy roads and potential flight delays across the region.
