It could be an exciting weekend on the water or the sand, whether that sand is on the beach or in the desert.
Mother Nature is kicking up her heels and you need to be aware of a couple of potentially hazardous weather situations.
A flash-flood watch is posted for the mountains and deserts. The monsoonal flow of subtropical, moist air out of Mexico has increased. This, in turn, has increased the possibility of thunderstorms in the far East County. Some of these storms are expected to be slow moving, which means they can produce a lot of rainfall in a very short period of time.
At the coast, where a lot of people are expected to congregate, high surf could pose a danger. A large South Pacific swell could produce waves up to 10 feet along some south-facing beaches, at least those north of Oceanside. For most of the county's coastline, however, 4-8 feet sets are probably more realistic. Higher-than-normal surf conditions also produce strong rip currents, so be sure you know how to handle these "under the surface" currents before you enter the water, and always swim where the lifeguards can see you.
