A storm makes its way across the Central Coast today, bringing the most rain mid-Tuesday into early Wednesday with a chance of thunderstorms.

Some parts of San Luis Obispo and Santa Barbara Counties saw light rainfall early Monday, however the remainder of Monday looks to be dry until light showers creep in again overnight.

Light rain develops early Tuesday south of San Luis Obispo County then gets heavier and more widespread north through the area late morning and afternoon.

The peak of this storm happens Tuesday afternoon/evening bringing the most amount of precipitation and instability.

Most coast/valley locations could see 1-2" of rain by Thursday with around 3" in the mountains.

With thunderstorms, rainfall rates up to an inch per hour are possible, but the National Weather Service has not issued any flash flood watches.

Wind gusts have the potential to reach 25-30 mph and look to increase to a peak 50 mph Tuesday as the low pressure system intensifies.

Here are potential impacts from this storm:

  • minor mud and debris flows near recent burn scar areas
  • rock falls on canyon roads
  • street flooding and traffic delays
  • possible beach lightning
  • possible waterspouts over ocean

Temperature-wise, daytime highs will actually be fairly close to normal and in the 60s for most of the area.

The rain will start to taper off Wednesday and the area will be left with scattered showers.

A strong onshore push makes its way in on Saturday bringing a deep marine layer and a potential for light drizzles.

Another storm is right behind and approaches from the north Sunday into Monday.
