Southland "Carbon Footprint".

(Downtown L.A: As seen from NB 5 FWY)

Did you know Los Angeles metro area is the second greenest city?

It's true... according to the Brookings Institution (D.C. think tank).

The Los Angeles metropolitan area emits less planet-warming carbon per capita than any big city except Honolulu, at least by some criteria.

In a report to be released Thursday on energy use in residential buildings and highway transportation, Brookings ranks Los Angeles as greener than New York, with its network of subways; more virtuous than Portland, Ore., with its smartgrowth greenbelt, and, yes, even better than San Francisco, its eco-vain rival.

Three other Golden State cities -- San Jose, San Francisco and San Diego -- rank among Brookings' top 10 in small per-capita footprints.

Thursday's outlook

A continued onshore push of air will result in night and morning low clouds and fog along the coastal plain and valleys on Thursday.

A Sneak Peak at the coming weekend

(Manhattan Beach/The Strand)

Overview...
...High pressure will build westward from the southern plains. This will bring warmer temperatures and shallower marine layer over the weekend.

Daytime temperatures...
Beaches... middle to upper 60s
Coastal plain... middle to upper 70s
Coastal valleys... upper 70s to near 80
Inland valleys... lower 80s

Looking ahead to next week...
...High pressure will move east again...allowing a trough of low pressure to move eastward... resulting in a "June Gloom" pattern!

A look at the rest of the week's weather for the southland

(Morning overcast - Sunday, May 25th, 2008)

Weekend getaway

(Snow: Near Flagstaff, Arizona - Friday, May 23rd, 2008)

Some southlander's experienced snow on their way to their holiday getaway on Friday.

Other popular weekend destinations that have had snow...
*Several locations in the Sierra's

the Grand Canyon.

L.A. and San Bernardino county mountains.


 

Below normal eastern Pacific hurricane season

(Infrared Satellite Image - Eastern Tropical Pacific)

FROM NOAA:

Climate conditions point to a below-normal hurricane season in the eastern Pacific this year... according NOAA's Climate Prediction Center.

The Climate Prediction Center outlook calls for a 70 percent probability of a below normal season, a 25 percent probability of a near normal season, and a 5 percent probably of an above normal season.

Allowing for forecast uncertainties, seasonal hurricane forecasters estimate a 60 to 70 percent chance of 11 to 16 named storms, including five to eight hurricanes and one to three major hurricanes (category 3, 4, or 5 on the Saffir-Simpson scale).

An average eastern Pacific hurricane season produces 15 to 16 named storms, with nine becoming hurricanes and four to five becoming major hurricanes.

Among the factors influencing this year’s eastern Pacific outlook are the multi decadal signal – the atmospheric conditions that have decreased hurricane activity over the eastern Pacific Ocean since 1995 – and the expected lingering effects of La Niña.
