BUFFALO, N.Y. (AP) — Families rushed to pack up their valuables and schools closed in advance — not of snow but possible flooding. Temperatures were expected to hit nearly 60 degrees on Monday, causing Buffalo area residents to prepare for evacuations caused by runoff from melting snow, and overflowing creeks. The National Weather Service has issued a flood warning for Monday and cautioned that trees weakened by heavy snowfall and saturated soil could come crashing down.
