Torrential downpours sweep southern California

Severe rainfall battered West Hollywood in southern California, US, on September 15, 2015. Substantial amount of precipitation triggered strong floods in the area, which prompted evacuations of over 100 residents, although no casualties were reported so far.

Torrential downpours have been brought to the parts of southern California by the low-pressure system, a remnant of the Hurricane "Linda" that formed southwest of Baja California on September 6.

The much needed rain has provided some relief from the hot and dry conditions prevailing so far, as the temperatures have dropped to about 21 ºC (70 ºF) in some areas.

As a strong rainstorm swept West Hollywood, thousands of locals have been cut off the power supplies, while torrential rains disrupted traffic and lead to water rescues across the affected areas.

"When units arrived, they saw leaking throughout the third floor, water coming down. The roof is under construction. There are many buckets and steady leaks throughout the building, throughout the whole third floor. We started evacuating the third floor due to the fact that the water is getting into the light fixtures, making it a safety hazard and electrical hazard," said L.A. County Fire Inspector David Dantic.
