Storm battering California sets record low pressure mark

By: Dr. Jeff Masters , 3:53 PM GMT on January 21, 2010

One of the most powerful low pressure systems since record keeping began in the 1800s slammed the West Coast yesterday with hurricane-force wind gusts, large hail, and torrential rains that have created flash floods and dangerous debris flows. The storm, centered just offshore near the Oregon/California border this morning, set an all-time record for the lowest pressure ever recorded along the southern Oregon coast yesterday. Medford, Oregon hit a pressure of 978 mb (28.88") yesterday afternoon, beating their old lowest ever pressure of 28.93" set in 1995. Northern California came close to setting a new record for lowest pressure as well, as Eureka, California hit 980 mb (28.93"), nearly matching the old record of 979 mb (28.91") set on Feb 22, 1891.

The storm, the latest and strongest of a series of El Niño-fueled storms to assault California this week, is expected to bring heavy rains of 1 - 3 inches over much of of the state today, wind gusts of up to 45 mph near the coast, and heavy snows of 1 - 2 feet to the Sierras. Arizona is expected to receive heavy rains of up to five inches from the storm. The storm will wind down by Friday, and California will have brief respite Saturday, before the next storm hits on Sunday and Monday. Sunday's storm should be much weaker, and the state will get a chance to dry out Wednesday and Thursday. However, another parade of storm is forecast to impact the state beginning on Friday the 29th, according to the latest long-range forecasts of the GFS and ECMWF models.

Severe weather in central California
The cold front associated with the strong low swept inland yesterday afternoon over central California, triggering heavy thunderstorms that brought hail and heavy rains in excess of two inches to some locations. A rare tornado warning was issued for Morgan Hill in the San Francisco Bay area at 2:02pm, when Doppler radar revealed a rotating thunderstorm. No touchdown of a tornado occurred, though 1-inch hail was observed in Morgan Hill. The Storm Prediction Center (SPC) has placed Los Angeles and San Diego in the "Slight Risk" region for severe weather today. The primary severe weather risk will be damaging thunderstorm winds, though a few tornadoes and waterspouts may also occur.

Snowfall amounts of 1 - 2 feet were recorded in the Sierra Mountains yesterday, with up to 4 1/2 feet of snow expected to fall by the time the storm ends on Saturday. Some precipitation amounts from the storm, for the 4-day period ending at 4am PST today:

Major Cities:

Los Angeles 2.80
San Francisco 3.49
Sacramento 2.35
Eureka 2.78
San Diego 1.65
Fresno 1.33

Sierra Nevada sites:

Chilkoot Meadow 7.08
Kaiser Point 6.60
Tenaya Lake 6.54
Graveyard Meadow 5.64
Tamarack Summit 5.36
Yosemite Village 4.04

Tornadoes, severe weather in the South
Tornadoes tore through Texas and Louisiana yesterday, with one twister destroying several homes and businesses near in Waskom, Texas, near the Louisiana border. Fourteen tornado reports were received yesterday by the Storm Prediction Center (SPC). SPC has placed portions of Alabama, Georgia, Mississippi, Tennessee, and Florida under their "Slight Risk" region for severe weather today. Already, there have been tornado warnings posted this morning for the Florida Panhandle, and southern Georgia.

Portlight successfully gets much-needed water filtration systems and medical supplies into Haiti
Portlight.org, the disaster-relief charity that has sprung up from the hard work and dedication of many members of the wunderground.com community, has successfully shipped medical equipment and a water filtration unit capable of supplying the needs of 3,500 people per day to the Dominican Republic, where was trucked to Haiti via road. These supplies have now made it to the earthquake zone, and have been targeted to go to those with disabilities, or who are living in areas where the main aid efforts have forgotten. Portlight is working through the local Catholic Church, which is probably best positioned to deliver private aid donations to those in need. Paul Timmons, leader of the Portlight relief efforts, wrote this to me yesterday:

Thanks to Wunderground blogger Dak Simonton (Dakster) we were made aware of Richard Lamarque, a Haitian expatriate and 15 year veteran of the Miami Police Department who was planning to go back to Haiti this week to look for family members and to help with recovery efforts. Our on scene coordinator, Richard Lamarque, will be leaving for Haiti in a few days. He is from there, is well connected there, and has a skill set and life experiences which will be invaluable to our work there.

We want this to be a uniquely Weather Underground community initiative. We will place WU signage on the truck...and we will be able to post photos of it at work in Haiti.

The Weather Underground community has been the genesis of our efforts. And the WU truck will be a long term, tangible symbol of the generosity of the WU community.



Figure 3. Walkers and medical supplies for Haiti getting ready to ship from the Portlight warehouse in Atlanta.

Thanks to the generosity of its donors, Portlight has been able to fund purchase of the truck for Richard Lamarque. Please visit the Portlight.org blog to learn more. Floodman's blog has the latest info on Portlight's plan for Haitian relief. The Reeve Foundation, founded by Christopher and Dana Reeve has awarded Portlight Strategies a $10,000 Quality of of Life grant to assist in the relief efforts in Haiti. This is very big and will allow Portlight to pursue more aggressive relief efforts over the course of the next few weeks.

For those of you more interested in helping out with the long-term rebuilding of Haiti's shattered infrastructure from the quake, I recommend a contribution to Lambi Fund of Haiti, a charity that is very active in promoting reforestation efforts, use of alternative fuels, and infrastructure improvements at a grass-roots level in Haiti. I've developed a great respect for the work they do in the country in the five years I've been a supporter.

Someone posted the theory that weather events may play a role in earthquake occurance. Is it possible that the incredibly large area of record cold that reached all the way to Cuba and for a sustained period, caused contraction of the earths outer crust thus causing the faults in the Carribean to move??


No. And a big area of high atmospheric pressure could not have had an effect either. ;) What'a a few mb, or degrees C, when you are talking about all that water and rock? But then again, the surface area is large, the fault area is small, and it might have been ready to go anyway... Who knows for sure?

The United Nations Development Programme (UNDP) employed nearly 400 Haitians in cash-for-work activities to jump start the local economy and facilitate the delivery of urgently needed humanitarian assistance. By the end of the week, this programme will expand to include another 700 people working on rubble removal and the rehabilitation of essential social infrastructure, such as street repairs and electricity.
As the co-ordinator of the UN early recovery team, UNDP is also working with the Government of Haiti and other partners to assess damages and needs, devise plans for rebuilding, and begin these immediate responses.
The first phase of the cash-for-work programme will focus on Carrefour-Feuilles, a neighborhood just south of Port-au-Prince. The initiative will soon be rolled out in other earthquake-stricken locations, including Leogane and Jacmel. Once fully operational, the project will employ 220,000 people, indirectly benefitting around 1 million Haitians
Past UNDP cash-for-work programmes in Haiti have laid the groundwork for this current initiative. After the 2008 hurricanes that killed 800 people and left 165,000 families homeless in Haiti, UNDP worked closely with the Haitian Government on reconstruction efforts, particularly focusing cash-for-work initiatives and watershed rehabilitation.
The cash-for-work programme launched Tuesday builds on UNDPs Briquettes Project, a cash-for-work programme designed to combat climate change and reduce poverty. To speed up the rubble clearing process, UNDP, as a first step, used the resources and staff previously employed by the Briquettes Project. But UNDP is currently in the process of selecting the additional 700 people to be employed by the end of this week.

Bio-briquette production saves environment, increases income

People of Dumarwana VDC, Bara district have been producing and using briquettes for cooking as it greatly helps in reducing indoor pollution. Briquettes are used as substitute for firewood and kerosene and it hugely reduces carbondioxide emission.

The production of bio-briquettes has added a new dimension to the lives of women as it has also become a source of income for them. The women earn up to Rs. 6000 per month by producing briquettes. One group (3-4 women) produces around 1000 briquettes per day. “There is intensive labour involved in the production as everything is done manually but it is good to have something than nothing,” say the women. The income helps them to pay their children’s school fees and run the household.

In order to increase income and expand business, these enterprising women are still looking for further opportunities as the production of briquettes is seasonal only. The project is supported by UNDP/ GEF Small Grants Programme.

It is not clear to me which technique they exactly use to create those bio-briquettes.

Just thinking of how even the smallest change in latent heat temperature over such a large area of land such as what happened a few weeks ago could translate into fractional contraction. The slightly cooled large land mass is attached to what is beneath the ocean and any movement would affect the seafloor as well. It is ironic that about the time the extreme cold was lifting out of the Southeast there was also widespread seismic activity in the Carribean.


Coincidental, but not ironic.

Haiti contributions deductible for 2009 taxesBy Hibah Yousuf, staff reporterJanuary 21, 2010: 5:50 PM ET


NEW YORK (CNNMoney.com) -- The Senate unanimously passed legislation Thursday that will allow taxpayers to deduct cash donations to Haiti earthquake relief on their 2009 tax returns instead of having to wait to file the claims next year.

If I had money I'd be a survivalist!! Buy a spead of land, plant the garden, get some livestock, invest in the solar panels and most importantly hoard supplies.

But I don't so guess I'll get through a week if the worst ever happens.

I garden extensively. Got 400 square feet worth. Trust me it's not enough at all.

As to electricity the second a dying neighbor sees a light on in your house he's grabbing his gun and he's kicking your door down.

You just can't do that. Once anyone sees you're doing good they are going to want in on it. And they'll take it by force if necessary.

Think about it. Would you sit idly by while you watch the guy next door eat well and have light and heat while you're starving and freezing to death?

No, you wouldn't...no matter how good of a person you are.

It's just the reality of it all.

I do pity anyone who tries to kick my door down. They're not getting far. Kinda sucks for me though. Cleaning up the mess.

This garden is an good example :)


You need to colaborate with your neighbours and before such a situation is occuring you can hope for the government to establish something in advance?
Basicly you need energy and the place to grow something. And it depends, you would not be the only one with electricity, and i don't talk about an anarchy scenario. Well ;)

Perhaps. I think most people would go insane in a hurry. Living where I do in New Jersey...we wouldn't have much time. Resources would run out rapidly.

You need a water purification/filter system (not too expensive but you need to re-supply fresh filters too).
Perfect is you have your own wind and/or solar energy generator (which can be build from trash - you need some special parts though, which can be bought relativly cheap - there are videos on youtube). Of course if you wise you have already an electric powered vehicle ;)

Food will be a tuff one, but you can grow food, even in your home. What you need therefor is seeds.

Of course you need a home which can handle tornadoes, flooding, hurricanes and earthquakes. Which can be done just from trees basicly - you would need a basement though which is kind of solid and a water pump maybe. Ok maybe not only trees but those can handle earthquakes and flood at least.

It is defintly doable and i guess the future for some effected areas.

no idc if anyone responds or not.. just like showing sum info.. But tampaspin aka Tim has a good site and links to go too.. but again anything more than 3 days out isnt certain.. but its worth looking at and just in case if it does come true or not.. right now models are agreeing and disagreeing.. just a matter of time they will agree or they go to another route..

Authorities say mudflows likely in drenched Calif.
Link

By JOHN ROGERS, Associated Press Writer
1 hr 39 mins ago

LA CANADA FLINTRIDGE, Calif. – Steady rain fell Thursday on saturated Southern California as the fourth Pacific storm in a week came ashore, triggering dire warnings by authorities that mud flows were likely in foothill communities and residents of endangered homes should obey evacuation orders.

Travel snarls mounted as a major highway was closed by snow and strong winds forced cancellation of dozens of flights at several airports.

The siege of storms has led to several deaths statewide and flooding in urban areas and on freeways.

Officials appeared concerned the lack of massive debris flows from wildfire burn areas was misleading for residents.

"It's time to roll, it's time to evacuate," said Los Angeles County Public Works Director Gail Farber.

County Fire Chief Deputy John Tripp bluntly warned that significant debris flows were likely and probably would block potential rescue attempts.

"For those people that are still in the homes and are in those areas of threat, it's very likely we will not be able to reach you," he said.

In the upper reaches of suburban La Canada Flintridge, where mountainsides rise sharply from the backyards of homes, authorities put pink ribbons on the mailboxes of residents who stayed behind so they would know where to search in the event of a catastrophe.
