A low pressure system is taking its time moving along the coast, southwest of Point Conception Tuesday morning. As of 4:11 a.m., very little rain had fallen and most morning rainfall totals were below .10''.

Morning commuters will be met with light, scattered rain through rush hour, but the brunt of this storm system isn't expected until Tuesday afternoon. Starting around 12:00 p.m. not only is rainfall expected to become moderate to heavy, but the chance for thunderstorms comes into play. The threat for thunderstorms will carry over to Wednesday morning.

Some of the impacts from thunderstorms include:
-Roadway flooding
-Minor debris flow near recent burn areas
-Rainfall rates from 0.25''-0.50'' per hour
-Localized wind damage
-Development of waterspouts off the coastlines

The predicted rainfall totals with this system have started to back off, amounts for the beaches and coastal valleys could be closer to 0.75''-1.25''. Still, for the mountains and foothills, there's a possibility for totals to reach 3''.

South to southeasterly winds will also be gusty at times, ranging from 25-40 miles per hour. A wind advisory will remain in place for Santa Barbara County through 1:00 p.m. as a result of these gusty conditions. Daytime highs will still be near normal, mostly ranging from the low to upper 60s.
