SANTA CLARITA — One of the strongest storms to hit Santa Clarita this year dropped a scant half-inch of rain on Friday, but left a mess on local roads. While there were no serious injuries, dozens of collisions were reported on city streets and freeways. The local office of the California Highway Patrol received 54 calls, but just a handful required law enforcement aid and none involved serious injuries, Officer Michelle Esposito said. “We were going from call to call to call,” she said. About 10:15 a.m., a car and big rig tangled on the northbound Antelope Valley Freeway near San Fernando Road, causing the truck to jacknife and the car to overturn. Less than 5 inches of rain has fallen in the region since Oct. 1, compared with an annual average of 16.4 inches. The year is expected to be the driest on record. Today will be partly cloudy with highs in the mid-60s and lows in the upper 40s, according to the National Weather Service. There’s a 40 percent chance of light rain in the afternoon, the weak tail end of Friday’s storm. Monday through Friday will be mostly clear and warmer.
