Hurricane Hilary will weaken to a tropical storm as it approaches Southern California this weekend. Here is Friday’s NWS Los Angeles forecast: There could also be lightning which, if the storm hits some areas with wind but without rain, could create fire danger. Thursday, the NWS issued a flood watch for Los Angeles and Ventura Counties “from sunday afternoon through Monday evening.” According to the Weather Channel, flood watches have also been issued for much of San Diego, Orange, Imperial and Riverside Counties. “Rainfall amounts of 2 to 4 inches, with isolated amounts in excess of 8 inches, will be possible across portions of southern California and southern Nevada,” per the latest NWS update.Īugust is generally L.A.’s driest month, with an average annual rainfall of 0″. The official rain total forecast currently is around 1″-2″ area-wide Sunday through Tuesday but with the potential for much higher (or lower) amounts depending on the actual track. So the probability of a very anomalous rain event is certainly increasing. That rainfall currently is pegged at a large accumulation for summer in Southern California with, per the NWS, “several solutions at or above 2.5″ and as high as 2.9” and “100 percent chance of rain” for much of Los Angeles. However, having said that, virtually all the GEFS ensemble members show moderate to heavy rain amounts, especially south of Point Conception.” A recent National Weather Service forecast for Hilary indicates: “There remains a very large spread in the ultimate track so this remains a very low confidence forecast in terms of the track as well as the impacts. Still, hurricane tracks are tricky to predict, especially days out. Normally, 67 or 68 degrees is the warmest coastal ocean temperatures get in the summer in Los Angeles.
This year’s El Niño event means ocean temperatures are much warmer than usual, with the water in Malibu registering 70 degrees today. Two factors tend to keep Southern California safe from such storms: colder sea surface temperatures, which take their fuel away, and upper-level steering winds in the eastern Pacific. Per NWS, “A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours.” No tropical cyclone has made landfall in California at hurricane intensity in recorded history.Įarlier today, the National Weather Service issued the first-ever tropical storm watch for Southern California. Only one full-blown tropical storm has hit the coast of California in recorded history: the Long Beach tropical storm that made landfall near San Pedro in 1939, according to the NWS. On the forecast track, the center of Hilary will approach the Baja California peninsula over the weekend.Ĭurrently, per the NWS, “Hurricane-force winds extend outward up to 60 miles (95 km) from the center and tropical-storm-force winds extend outward up to 275 miles.” A turn toward the northwest is expected Friday morning, followed by a turn toward the north-northwest and north on Saturday.
Hilary is moving toward the west-northwest near 14 mph (22 km/h), and this general motion is expected to continue through tonight. Here is more on the storm’s direction from the National Weather Service: That means Hilary is expected to still be a tropical storm while roughly over San Diego County. More substantially, for the first time it has the track over Southern California with the letter “S” attached.

But that could mean that drier regions inland face the center of the storm plowing right over them, dropping a full year’s worth of rain in 24-48 hours.

Late Thursday, NWS update also shifted the predicted path of the storm eastward, which could bode well for coastal population centers such as L.A., Orange County and San Diego. The storm was about 360 miles SSW of Cabo San Lucas by late morning on Friday.
