Los Angeles weather

[Mike M]

For my first report on Los Angeles, we are seeing above average temperatures, albeit not as hot as it was earlier this month when LA went up well into the 90's. Highs today were still a good 10-15° above average. Temperatures will cool down to near average by next week.

Just so there's no confusion, the "Civic Center" title you see on the map and current conditions page refer to the downtown area in Los Angeles. I've seen several sources (including the WeatherStars) that use that name so I decided to use it here.

Just as is the case with Sacramento, unseasonably hot weather can be found in the Los Angeles metropolitan area
today. Temperatures are well into the 90s this afternoon in the high majority of locations across southern California
with the exception being literally right at the coastal spots. That's where you can escape the heat by hitting
the beach where readings are in the 70s and 80s.

This heat wave that is making its presence felt up and down the west coast of the United States is expected
to last right through the entire weekend for Los Angeles and its surrounding suburban areas.

I will post the graphics pages as soon as I can.

It is an unusually chilly and damp morning in southern California with temperatures only in the upper 40s to low 50s and rain across much of the region. Roughly 20 miles west of Los Angeles, you will find much better sky conditions and better visibility.

After the recent wildfires, there are flood advisories that have been posted by the National Weather Service for the burn areas. Much of Los Angeles County is under the Flood Advisory until noon today. See the weather statements below for more details.

It will remain unsettled for at least the next 24 to 36 hours with a chance of more showers through at least tomorrow night.

SPECIAL WEATHER STATEMENTS by the National Weather Service in Oxnard, California on December 15, 2008
A FLOOD ADVISORY is in effect for Los Angeles County until 12:00 PM Pacific Standard Time.

The National Weather Service in Oxnard has extended the flood advisory for Los Angeles County in southwest California until 12:00 PM Pacific Standard Time.

At 9:50 AM, Doppler radar indicated moderate to locally heavy rain continuing across much of Los Angeles County. The highest rainfall intensities will be focused across eastern Los Angeles County with rates between ¼ inch to ½ inch per hour. Storm totals have ranged between one and three inches across the Los Angeles basin. Urban and small stream flooding will continue across portions of the County through the remainder of the morning hours.

Do not drive your vehicle into areas where the water covers the roadway. The water depth may be too great to allow your car to cross safely. Move to higher ground.

A flood advisory means river or stream flows are elevated or ponding of water in urban or other areas is occurring or is imminent.

A FLASH FLOOD WATCH remains in effect through this afternoon.

The Flash Flood Watch continues for the recent burn areas in Los Angeles County including Santa Catalina Island in southwest California.

Through this afternoon rainfall rates could exceed one half inch per hour through this afternoon.

Flash flooding and debris flows will be a particular threat in and below recently burned areas.

A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation.

Southern California residents in or near the recently burned areas are urged to take The Steps necessary to protect their property. Persons in the watch area should remain alert and follow directions of emergency preparedness officials.

More information from the USGS on debris flows and their impacts can be found at http://landslides.USGS.Gov/research/wildfire (all lowercase letters)

PLEASE NOTE:
I was unable to add the local radar view at the time I posted this report because the animated file is too big in size.
I hope to add it as soon as I can.
