Tidal overflow could bring brief minor flooding in low-lying areas and along parts of Highway 101, and officials urge people to stay out of the water and prepare for high-tide inundation.

Overview

  • Forecasters say tidal overflow flooding is expected, with minor inundation up to about 1 foot in bays, sloughs, and the lower reaches of coastal rivers.
  • Portions of Highway 101 could flood, including areas near Raymond, Seaside, and Fraser Road in Tillamook County.
  • A separate Coastal Flood Watch is in effect for the South Central Oregon Coast on Thursday from 4 a.m. to 10 p.m., with possible minor tidal flooding, low-lying road closures, and dangerous surf.
