SLO County braces for more flooding, slides and downed trees

January 13, 2023

Flooding next to Highway 101 in SLO earlier in the week

The rain is slated to arrive early in the day on Friday and continue intermittently through Monday. And while the storms are expected to bring lighter rainfall than earlier in the week, the ground is already saturated.

As a result, additional power outages, flooding, mud and debris slides, and downed trees are anticipated. Emergency personnel are warning the public to be prepared and careful as the storm approaches.

It appears maybe the millions of SLO and SB counties tax payer dollars spent on cloud seeding is working ? Seems all the other counties in California now owe SLO / SB counties some money for the 300 plus inches of snow at Tahoe and the atmospheric river rain covering the entire state of California. Just for grins I wonder if the Montana based cloud seeding company has any friends or relatives who have pull in local government spending ?

Yeah right… SLO and SB county has been flying planes in the middle of the pacific to seed these atmospheric river systems… I hope you have that tin foil hat ready!
