As the last of three major storms moved into the Southern California region, a coastal flood watch was in effect through Wednesday night, January 20th and high surf conditions are expected at Los Angeles County beaches through Friday, January 22th, the National Weather Service advised.

The combination of the three storms, which began earlier in the week, has produced the most rain in the region in years, local weather analysts said. A large westerly swell that arrived January 19th has caused high surf conditions along beaches, as well as strong winds and high waves across coastal waters, according to the National Weather Service.

The surf conditions were predicted to peak by January 21st, when breakers could reach as high as 25 feet. Flooding of low-lying coastal areas can be expected with the conditions through January 22nd, the service warned.

The service has also advised swimmers that dangerous rip currents are anticipated through much of the week and even the most experienced swimmers are encouraged to stay out of the water during that time. Rocks and jetties can be especially dangerous areas for beachgoers.

The U.S. Coast Guard has urged mariners and beachgoers to exercise extreme caution in and around coastal California waters throughout the week. The agency urges any mariners who use the waters to check all of their safety equipment to ensure it is in good condition and working properly.

All boaters should also ensure that they have a working marine-band VHF radio to contact the Coast Guard on channel 16, an emergency frequency, should an emergency arise.

Mariners should also check current and forecasted weather conditions prior to getting underway, and remain aware of changing conditions once on the water, the Coast Guard said.
