Third storm rolls in Wednesday with thunder, hail and (possibly) weak tornadoes
2010-01-20 · By Editor
A “powerful and vigorous storm system” will take hold of Southern California Wednesday, says the NOAA. The third in a four-storm onslaught, it will bring the “potential for strong thunderstorms, damaging winds, heavy rainfall and high surf slamming many of the coastal areas.
The rain is expected to arrive late Wednesday morning and last through Wednesday night with the heaviest rainfall between 10 a.m. and 8 p.m.
The latest system to hit Long Beach will be incredibly unstable. Some of the thunderstorms may produce hail, wind gusts in excess of 60 mph and torrential downpours. Atmospheric conditions will once again be favorable for isolated weak tornadoes which could form over land or move ashore after forming as waterspouts.
Very strong and potentially damaging winds are also possible through the night bringing with it downed tree limbs and branches. According the the NOAA, this powerful storm has the potential to bring some the strongest winds seen in over a decade to much of southwest California.
In the mountain areas… the winds will combine with the falling snow to produce near blizzard conditions and local white out conditions possible… mainly above 5000 feet. Snow accumulations up to 6 inches locally will occur and combine with the winds gusting to possibly near 75 mph making travel through the mountains treacherous. Traveling through the mountains will be highly discouraged on Wednesday and Wednesday night.
High surf will continue to pound southwest and west facing beaches and harbors at least through Wednesday night. High tides will occur around midday on Wednesday… presenting a threat for widespread coastal flooding in low-lying areas. Swells in excess of 20 feet are possible for central coast beaches and harbors… with the potential of swells in excess 10 feet for area beaches from Rincon Beach south to Redondo Beach.
