Wind & fire

(Smoke Filled Sunrise - Tuesday, May 23rd, 2006)

With it being a long...holiday. Many will being heading to the great outdoors... such as the mountains.

Be very carefull if you plan on having a campfire...as conditions are very dry. As all it takes is one spark or flying ember. Also...with the high winds predicted for the mountains for the most of the weekend...this will just add to the fire danger.

Many state and national recreation areas have restrictions regarding campfires and bbq's.

Have a "safe" holiday weekend!

Dirty beach sand?

(Santa Monica Beach - July 25th, 2005)

A new U.C.L.A. study shows that polluted seawater is not the only threat for southland beach goers.

Researchers say that high levels of bacteria has been detected at some southern California beaches.

Some of the beaches that researchers have detected high-levels of bacteria from Redondo Beach to Malibu.

Some of the worst offenders were sheltered side of Cabrillo Beach in San Pedro, Mother's Beach in Marina del Rey, Santa Monica Beach near the pier and Topanga Beach in Malibu. Sheltered or enclosed beaches showed persistent elevated levels of bacteria.

Storm inching closer

(Pismo Beach at Twilight)

***Update: 3:35pm/pdt, Saturday, May 20th, 2006***
Clouds will be on the increase across much of the southland Saturday night.

There will be a slight risk for showers late tonight over the Santa Barbara County.

Rain will gradually increase over southern California. Reaching Los Angeles county sometime during the late morning or afternoon hours. The rain will continue to spread across the remainder of the southland during the afternoon hours Sunday...with widespread rain expected Sunday night through Monday morning. Rain is expected to turn to showers during Monday afternoon.

At this times... models are suggesting amounts will be in the range of 0.50 to 1.50" from L.A. County...northward.

In Orange, San Diego County and the Inland Empire amounts will be in the 0.25 to 0.50" range.

Locally heavier amounts are likely along the foothills and south/southwest facing mountains slopes.

Snow will be possible over the higher elevations of the mountains with accumulation possible.

The potential continues to exist for isolated thunderstorms. Some of these storms may produce... gusty winds, small hail, dangerous lightning and locally heavy rains. Funnel clouds or waterspouts are a possibility over the coastal waters. There is also a slight possibility of even a brief tornado over the Los Angeles basin.

Mountain tstorms

(Towing Cumulus clouds - 10:50 am, May 18th, 2006)

Like the past couple of afternoon... There will be a slight chance of afternoon and early evening thunderstorms over the mountains and high deserts on Friday.

But... unlike the past couple of days... the storms that develop Friday will primarly be in Los Angeles, Ventura and Santa Barbara county mountain areas and in the Antelope valley.

***Updated at: 4:40pm/pdt Friday, May 19th, 2006***
There's a major change late in the weekend... back to winter like weather.

A fairly strong upper level trough of low pressure (presently over the eastern Pacific) will move inland Sunday.

This system will bring widespread rain to the southland beginning Sunday afternoon and continue into Monday morning.

It's still up in the air how much precipitation will fall. But... the potential does exists for up to 1.00" over some coastal and valley locations. And as much as 1 to 3" possible along some coastal foothills and south-facing mountain slopes. There will also be risk of isolated thunderstorms with this system along with the likelyhood of gusty winds (especially at the time of the frontal passage).

Snow levels will lower over the mountains with the possibility of several inches of snow in some locations.

Further updates as needed!

Colorful Palms

(California Incline - Santa Monica)

More of the same expected Thursday...

Mostly sunny to partly cloudy skies excepted across the southland during Thursday...except for morning low clouds and fog...coastal and valley areas.

Don't rule out isolated thunderstorms over the mountain and desert areas during Thursday afternoon and early evening.

On Wednesday... a lightning strike sparked a brush fire in the Antelope Valley.

As for the daytime high temperatures on Thursday...
Coastal areas... 60s and 70s (middle 70s downtown L.A.)
Valley areas... upper 70s and 80s (except in the lower to middle 90s in the valleys of the Inland Empire).

Looking ahead...
A trought of low pressure may make for some interesting weather this weekend over the southland.

Still a bit early on what effects this will have here in southern California. But...the potential does exist for at least some shower and thunderstorm activity.

More details on this on later posts!

Pacific Tropical Weather Season Begins.

(An early morning moon set)

Today is the official start of the 2006 eastern Pacific tropical weather season.

Only once...in September of 1939 southern California took a direct hit from a Tropical Storm.

Happy Mother's Day!

(Re-Colorized Photo of Avalon, Catalina Island)

Nice day for all southern California mother's today!

The usual morning low clouds and fog along the coast and in the valleys...then becoming mostly sunny this afternoon...except partly cloudy skies along the Orange and San Diego coast.

High temperatures will range from the middle 60s to the lower 70s at the coast...to the upper 70s to the middle 80s in most valley areas...except upper 80s to the lower 90s in the San Bernardino/Riverside area.

Out in the low deserts... temperatures are likely to top the century mark later today.

Landscaped freeways

(The 163 Freeway - Balboa Park)
Why are some southland freeways landscaped so beautifully?
The primary reason for this... is for pollution control. Plants, trees and flowers naturally absorb pollution in return this somewhat limits the amount of pollution that excapes into the higher levels of the atmosphere.
But... during the past ten years or so... a lot of the landscaping has been removed. This is due to water conservation or for widening the freeways.

Hot inland areas

(Hot/Hazey Afternoon on the 15 FWY - Cajon Pass)

Sunny, hazey and hot conditions will continue in the valleys, mountains and deserts for the next several days.

Take precuation if you plan on being outdoors in these areas...such as stay in shadey areas...and drink plenty of water.

Thursday afternoon... several teenagers were overcome by the heat at San Fernando High School during an outdoor concert. One of the teenagers were hospitalized.

At the time of the concert temperatures were in the middle 80s.

So...be careful if you have to be out in the heat!!

As for the coastal areas...including downtown Los Angeles... The usual night and morning low clouds and fog with even some drizzle possible...then clearing to the beaches by afternoon.

Afternoon temperatures will be in the 60s at the coast to the lower to middle 70s downtown Los Angeles.

Sunsets and colors

Why are some sunsets so colorful...and others are not?

The simple answer to this question is...

Scattering of different wavelengths of sunlight by the particles and water vapor in the air.
A large amount of particles tend to scatter out blue light, giving us a pink to red sunset.
The red sunset can be washed out to whitish by heavy haze or high relative humidity, which will scatter all wavelengths more equally.


More beautiful sunsets!


As for Thursday's weather...in fact the rest of the week:
Night and morning coastal and valley low clouds and patchy dense fog...then clearing to the beaches by afternoon.

Afternoon high temperatures...
60s at the beaches...
70s downtown L.A....
and in the mostly in the 80s to the middle 90s in the valley areas.

Wednesday, May 10, 2006

More night and morning gloom

More of the same...

Night and morning low clouds and fog at the coast extending inland to the valleys.
Then clearing to the beaches by midday.

High temperatures...
60s at the beaches,
lower to middle 70s downtown L.A.

and in the middle 70s to the middle 80s in the valley areas.

No change in sight for at least the next week.

More low clouds and fog

(Gloomy Spring evening in Santa Monica)

No change in the prevailing weather pattern...

The "Catalina Eddy" will continue the ongoing marine layer over the coastal and valley areas of the southland through the rest of the week.

Expect night and morning low clouds and fog...with only partial clearing expected during the afternoon's near the beaches.

The marine layer will keep the coastal area temperatures on the cool side (mainly in the upper 50s to the upper 60s).

But... in the valleys...where there will be afternoon hazey sunshine...the temperatures will top out in the 70s...except in the lower to middle 80s in the valleys of the Inland Empire.

Monday, May 08, 2006

Same ol' pattern

(Somewhere of the coast of San Diego County)

Same old pattere to persist across the southland for the entire week. High pressure will dominate the region through at least Friday.

A weak circulation (Catalina Eddy) will continue the gloom along the coast...extending into the valley areas during the overnight and morning hours. This will help to keep the coastal area on the cool side...mainly in the 60s to the lower 70s. With afternoon sunshine expected in the valley areas...this will help them reach into the middle 70s to the middle 80s each afternoon.

If you want hot...head out into the low deserts this week... temperatures will likely be in the 90s each day. Only getting down into the middle 60s to the lower 70s at night.

Cool spring in southern Cal.

It's been a cooler than normal spring so far in the southland.

From February 15th through May 5th (80 days):
The mean temperature for downtown Los Angeles has been below normal for 67 days, exactly normal for 2 days and above normal for only 5 days.


The high temperature exceeded 70 degrees at downtown L.A. for only 8 days in April of 2006...far below the normal 16 days during a typical April.

This above mentioned data holds true for many other observation points across the southland.

Saturday, May 06, 2006

Not as much gloom for some

Not as much gloom for some during the afternoon hours.

Expecting night and morning low cloud...fog...and some patchy drizzle in spots through this weekend. But... skies will clear to the beaches from Los Angeles County northward during the afternoon hours.

Afternoon temperatures will range from the 60s at the beaches to the 70s in the valley areas.
Maybe a few degrees warmer (especially valley areas) on Sunday.


Swimmers and surfers... be advised of rip currents this weekend along the coast of Orange County.

To learn more about rip currents...including important safety information...besure to visit Southland Weather's special report on "Rip Currents".

Friday, May 05, 2006

Risk of Rip Currents

(Rip Currents - La Jolla Shores)

Swimmers and surfers are strongly advised to remain onshore through Saturday along the coastal waters of Orange County...due to a high risk of Rip Currents.

These conditions have the potential of impacting other beaches (especially the beaches of San Diego County) on Saturday. But as of now...no official forecast advising of the potential of Rip Currents has been issued from the NWS.

Thursday, May 04, 2006

The gloom continues...

(Gloomy May Evening at Seaport Village San Diego)

No real let up expected over the next several in the persistant marine layer.

from the coast to the lower slopes of the mountains... look for low clouds with patchy area of fog and drizzle through the weekend.

Temperatures will remain in the 60s for the most part. Maybe some lower to middle 70s out in the valleys of the Inland Empire.

Wednesday, May 03, 2006

Socked in...

(Low clouds over the Vicent Thomas Bridge)

Widespread gloom extending inland to the mountains Wednesday.
The Marine layer is apx. 3,100 feet thick. Which will mean that the fog will extend through some of the passes and canyons.

Along with low clouds and fog... areas of light rain or drizzle are possible.

There gloom is expected to stick around through Thursday morning...before there's any chance of seeing a peak of the sun.

I know this isn't weather related but...on this date back in 1939 Union Station opened it's doors to the public in downtown Los Angeles.

Tuesday, May 02, 2006

Record April Rainfall for some of us

(Summer Monsoon tstorm in the Mojave)

The National Weather Service in Oxnard on Monday reports that both LAX and Santa Barbara Airports had record rainfall during the month of April.

LAX had 1.63" of rain during April breaking the old record of 1.35" set back in 1999.

Santa Barbara Airport had 4.86" of rain in April. The breaks the old record of 2.83" set in the year 2000.

The May Gray

(Gloomy May San Diego AM)

The May Gray is here to stay a while here in the southland.

All areas west of the mountains will see low clouds and areas of fog (locally dense at times) through the week. The marine layer will clear to near the coast by the early afternoon hours. But will once again cloud up by 4 or 5 in the afternoon at most beaches.

Local drizzle is also possible in some areas...especially the far south coast including Orange and San Diego counties...and the valleys of the Inland Empire and San Diego County.

The marine layer will keep it cool at least along the coast and several miles inland during the next few days...that's in contrast to the heat that the southland desert areas are having.

Monday's high temperatures are expected to range from the upper 80s to near 100 with no let up in the heat expected all week.
