A National Weather Service high surf advisory for 5- to 8- foot surf with sets to 9 feet south of Del Mar will expire at 6 p.m.
High surf and flooding from a sewage flow prompted the organizers of the binational “Surf the Border'' contest to indefinitely postpone the event, which was to be held off the coasts of Imperial Beach and Tijuana Sunday.
Forecasters said the latest in the series of swells would be somewhat larger, but one expected to hit Wednesday and Thursday will be the largest, with local sets of up to 10 feet. Another swell with 3- to 6- foot surf and sets to 7 feet will arrive next weekend.
The large waves and strong rip currents accompanying the swells could increase the risk of drowning, especially for swimmers with little experience in the water. Localized beach erosion may also be possible, forecasters said.
