This situation surrounding Hurricane Hilary has triggered the first Tropical Storm Watch warning ever issued for Southern California.
On the morning of Saturday, August 19, the National Weather Service moved up the start time for the Flood Watch in LA County to 10 am for Sunday, August 20, due to the storm's faster movement than what was predicted earlier.
