Wow, Tuesday afternoon's weather could not be more opposite of what we are expected to experience in the next 24 hours.

We had plenty of sunshine and even saw temperatures a few degrees warmer than Monday.

That's all about to change overnight.

The latest models show heavy rain starts to build over northern San Luis Obispo County shortly before 4 a.m..

Coastal areas of San Luis Obispo County could see three hour rain rates between 1-2 inches, causing roadway and creek flooding.

These rain rates meet the criteria to for a Flash Flood Watch to go into effect at 3 a.m. Wednesday.

When the system moves through Thursday into Friday, more Flash Flood Watches may be needed.

This storm is also dropping snow levels to 4500 feet Tuesday night. Mountains above 6000 feet should expect several feet of snow.

Mountain areas will also see gusts upwards of 60 mph, creating conditions for a Winter Storm Warning.

Winds are another large concern with this storm, as gusts up to 60 mph are projected for several areas across the Central Coast.


A High Wind Warning has been issued from 10 p.m. Tuesday to 10 a.m. Thursday for San Luis Obispo County, due to wind speeds estimated at 25-40 mph and gusts up to 65 mph.

A Wind Advisory has been issued from 10 p.m. Tuesday to 4 p.m. Thursday for Santa Barbara County, due to winds estimated at 20-30 mph and gusts up to 50 mph.

As the storm moves south however, it's like the wind advisory will be upgraded to a high wind warning.

Out on the water, dangerous conditions continue.

A High Surf Advisory has been issued until 6 p.m. Friday, as large breaking waves of 10 to
16 feet with dangerous rip currents are expected.

A Coastal Flood Advisory is in effect from 4 a.m. Wednesday to noon Thursday, as moderate coastal flooding expected - especially around Port San Luis during the morning high tides.
