Around 8:30 a.m. Saturday, a Postal Express truck was involved in a collision six miles southeast of Leavenworth. Brian Moore , a spokesman with the Washington State Patrol, sent out a tweet with information about the crash.

The State Patrol said most of the contents are harmless medical supplies, but some packages could pose a risk if unsealed. As water levels recede, more packages could become exposed.
