When Northwest weather guru Cliff Mass warns of “extraordinarily active weather with the potential ... to be an historic event,” it’s time to check the flashlights, get some water and non-perishable food and prepare to hunker down for a couple of days.

A high-wind warning has been issued for Thurston County from late Thursday through 7 a.m. Friday, with gusts peaking near midnight.
