The San Luis Obispo County Air Pollution Control District and County Public Health Department are advising the public of deteriorating air quality in the Oceano Dunes/Nipomo Mesa area due to blowing dust and sand.

Due to forecasted high winds, blowing sand and dust is forecasted to occur Wednesday, May 22 through Tuesday, May 28 from 11 am to 7 pm, with the dust forecasted to peak from 1 pm to 5 pm. Very sensitive individuals such as infants, as well as children and adults with existing respiratory or heart conditions may experience adverse health effects during blowing dust periods.County officials recommend that the public reschedule outdoor activities to occur when there is no visible dust. If blowing dust and sand is visible in the air, County officials recommend all adults and children avoid strenuous outdoor activity, remain indoors as much as possible, and set any heating/air conditioning/ventilation systems to recirculation.

The public is advised to consult your doctor if you are experiencing health problems in an area with blowing dust and sand. If staying indoors does not provide relief, temporarily leaving the area and going to a location where the sand is not blowing and dust is not visible is advised.

There are gale force northwesterly winds will continue across portions of the coastal waters through Thursday.

The building wind-generated waves will propagate toward the coast and produce large breakers at many of the west and northwest facing beaches.

As a result there is a high surf advisory in effect until 11 am Thursday.

Surf will build to 9 to 13 feet. Choppy wave conditions are expected due to strong winds over the waters. And the high surf conditions will continue through midday Thursday.

Large breakers and the high risk of rip currents will make swimming dangerous.
