Bomb cyclone storm impacts

A bomb cyclone windstorm lashed Bellevue the night of Tuesday, Nov. 19, bringing down trees throughout the city and leaving hundreds of thousands without power. Most city facilities have power but some are on modified hours or closed due to power outages. Damages from the storm continue to impact Bellevue. Updates about the city's response will be posted at Bomb Cyclone Storm.
