Rain, “strongest winds in over a decade”
Posted on | January 19, 2010 | 1 Comment
A NATIONAL Weather Service statement predicts along with heavy rain for Los Angeles on Wednesday January 20, 2010 “the strongest winds in over a decade.”
From the report: “The heaviest rainfall will spread into the area between 10 am and 8 pm on Wednesday. Rainfall rates will range from three-quarters of an inch to one inch per hour with local rates up to 1.50 inches per hour across south-facing slopes. Total rainfall accumulations will range from one inch to two inches over coasts and valleys with two to four inches in the mountains. Local amounts up to five inches are possible along south-facing slopes.
With the amount of instability with this system there is a high potential for strong thunderstorms to develop on Wednesday and Wednesday night. Some of the thunderstorms may produce hail, wind gusts in excess of 60 mph and torrential downpours.
Atmospheric conditions will also 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 over the area on Wednesday through night. By Wednesday night it could be highly possible of many storm reports of downed tree limbs and branches area-wide. Some coastal and valley areas may be unusually affected by strong and potentially damaging winds. This powerful storm has the potential to bring some the strongest winds we have seen in over a decade to much of southwest California.
