Getting reports of a flash of light and a loud boom heard in and near Grays Harbor County on the Washington coast. Given the numerous reports over a wide area it was probably a bolide -- a meteor exploding in the atmosphere. #wawx— Morgan Palmer (@MorganKIRO7) March 8, 2018

IF the flash in GH county was a bolide meteor, it might have hit the atmosphere an angle of about 45° relative to those who heard a sonic boom. It can take 1 1/2 to 4 mins for the boom to reach ground after the explosion.
The Federal Aviation Administration and the Western Air Defense Sector said they didn’t have any problems.
There also have been no reports of explosions or crashes on the ground.
Resident Derek Hnilica sent KIRO 7 video of the flash in Hoqiuam.
