Flooding Continues as We Prep for the Next Round of Rain & Wind
Here’s a look at your forecast for Santa Cruz, Monterey, San Benito, and southern Santa Clara Counties!
Muggy, showery weather continues Monday while we monitor the ongoing flooding of the Pajaro and Salinas Rivers. Waters from the Pajaro continue to spill out of the river channel into surrounding areas even though the river itself is receding. The Salinas River has been actively flooding along its course this weekend, but the crest has not reached the lower stretches yet. It is expected to crest Monday with potential flooding of Highway 68 and surrounding areas. All the while, the next storm system arrives late Monday into Tuesday and will utilize the moisture stream to create heavy rain once again. Damaging winds and flooding appear likely again, so remain vigilant. Beyond that system (which could last into Wednesday with additional showers), the weather looks a bit more tranquil toward the end of next week with one weaker system arriving on Friday.
