Although water-starved Southern California needs all the rain it can get, weather forecasters say the light sprinkles falling across the region Wednesday will likely only be enough to cause problems during the morning commute.
National Weather Service officials are expecting less than a tenth of an inch of rain from the cold front passing through Los Angeles. Meteorologist Kathy Hoxsie said the rain could be so light that it will only serve to lift oil off the roads without washing it away, creating slick conditions for drivers.
"We get concerned that if the rain is too light it can cause more problems," she said.
Two SigAlerts were already in place around 5:30 a.m. Wednesday. Two truck lanes of the northbound 5 Freeway near the 14 Freeway were closed after a big rig jackknifed, California Highway Patrol Officer Jennifer Cassidy said.
A westbound 210 Freeway transition road near the 134 Freeway was also closed by a jackknifed big-rig, she said.
The rain is expected to linger into Thursday but clear up by Friday, when Hoxsie said temperatures are expected to warm from the 60s into the 70s.
