A Disaster isn't necessarily over when it is over.

On Dec 4, 2017, the Thomas Fire erupted in Southern California, eventually burning hilly terrain of more than 281,000 acres,damaging the communities of Ventura, Montecito,and Santa Barbara. Fortunately, while there was widespread property destruction, only two people died - one in an auto accident fleeing from the fire.

January 8 considerable rain fell on the burnt hills above these communities, triggering massive mud flows which slammed into Montecito. The current death toll stands at 21, with two more still missing. Preparations were made for the flooding, but they were overwhelmed. Highway 101 was closed and will open on Monday. Traffic was diverted to Cal Highway 166, a narrow, twisting two lane road offering a round about access to Santa Barbara. Two days ago, there was a fatal collision on that road, a direct consequence of the heavy traffic. Use of that road is not now advised....

Problems with disasters don't cease just because the main event has ended...Cleanup can be especially dangerous.
