HALF MOON BAY -- San Mateo County's tsunami sirens are working again, a month after a routine test revealed most of the warning system wasn't functioning, officials said Friday.
A contractor has finished upgrades to the system, which had been out of service in August as the work was underway. The repairs were expedited after officials on Aug. 7 discovered only three of eight sirens were working properly in the system, which stretches about 30 miles from Pacifica to Pescadero.
The new system will be able to broadcast voice messages instead of just a warning tone, as was the case with the old equipment, said San Mateo County Emergency Service Office Coordinator Jeff Norris.
"This major advancement will allow the system to not only alert the public but to also provide directions about the nature of the emergency and the appropriate actions to take," Norris said.
The new system automatically tests itself every 12 hours, but officials still plan to turn on the sirens the first Wednesday of each month at 10 a.m. to make sure they are working.
