Significant Storm with Increasing Threat of Debris Flows in Southwest California this week.
A significant storm system will be developing off the California coast tapping into abundant subtropical moisture.
As a result, there is the potential for a very wet and long duration storm for Southwest California from Tuesday through Thursday night.
Heavy rainfall will impact our forecast area, but still not certain where.
There is increasing confidence that portions of our forecast area will receive significant rainfall with high rainfall intensities.
Potential for significant flash flooding and debris flows will be in and around recent burn areas, with the highest probability of higher intensity rainfall sometime between late Tuesday night and early Thursday.
In addition, there will likely be a threat of widespread urban roadway flooding as well as flooding of small creeks and rockslides.
