California fires could reach record levels in 2008

Posted by: Dr. Jeff Masters, 21:42 GMT le 25 juin 2008

An unusually early and dangerous fire season has hit California, where at least 33 fires burning over a total of 190,000 acres are active, according to the Interagency Fire Center. The fires were sparked over the weekend when an unusually far southward-moving storm system brought numerous thunderstorms to central and northern California. Over 8,000 lightning strikes hit the region. Most of these strikes were not accompanied by rain, since a very dry atmosphere at low levels caused much of the thunderstorm rain to evaporate before reaching the surface. The lightning strikes ignited an unusual number of fires, due to exceptionally dry vegetation in California. This year, the state experienced its driest spring season (March-April-May) since record keeping began in 1895, and much of the state is in moderate to severe drought.

Figure 1. Visible satellite image from NASA's Aqua spacecraft on Monday, June 23, 2008, showing smoke from hundreds of wildfires sparked by lightning in California. The red regions show where the satellite's sensor detected fires burning. The smoke has created air pollution levels in excess of the federal standards for fine particulate matter (PM2.5) over much of California's Central Valley. Image credit: NASA.

The forecast
With the dry season only beginning, it could be a record fire year in California. Even before last weekend's lightning storms, California had already seen an unusually large number of destructive wildfires, according to CalFire--90,000 acres had burned, compared to 42,000 acres during the same period last year. It is not unusual for large portions of the state to receive no rain at all in July and August, such as occurred last year (Figure 2). The jet stream typically moves far enough north in summer that the migrating low pressure systems that bring California most of its rain only hit the northernmost portions of the state. With high fuel levels due to a century of misguided fire suppression efforts, moderate to severe drought gripping the state, no rain in sight for months to come, and an above-normal chance of warmer than average temperatures forecast this summer for the state by NOAA's Climate Prediction Center, expect a record fire season in California.

Figure 2. Observed precipitation over California during 2007. Much of the state received no rain at all during July and August, which is a common occurrence. A little bit of thunderstorm activity did make it into the easternmost portion of the state, thanks to moisture flowing north-westward from the Arizona Monsoon. However, the Sierra Mountains block this moisture from reaching the central and western portions of the state. Image credit: NOAA.

Tropics
It's quiet in the tropical Atlantic. There are no threat areas to discuss, and none of the models are forecasting tropical storm formation in the next seven days. Beyond a week from now, the GFS is hinting that the region off the coast of Africa could see some development, but it is still probably too early for this too occur, despite warmer than average sea surface temperatures in the region.

On the lighting issue it is also good to see many athletic programs take it very seriously; I was at a Seminoles Football game last season and they did a "lightning delay of game" which lasted about 45 minutes; You could not see a cloud in the sky from the stadium, and, people were bitching, but, I'm certain that they were keeping an eye on local radar during the game and saw something that they did not like; Good for them in terms of the safety of the players and fans.......(one of the oldtimers in front of me was saying that he had been to every game for the last 10 years an he had never seen a lighting delay when it was not raining)....

Ike do you think that blob in the GOM might head toward Mobile,Al and bring us rain? Also do you think it will make it over the weekend? I was just wondering, thinking about going fishing. A good friend of ours lost there son about 2yrs ago during a fishing tournament, lightning struck him they where near the Dolly Parden Bridge well that's what we call the bridge.

geeze, look at all these lightening stories -- people, especially the horse people, think I am such a worry wart in regard to stikes --I remember my kid playing on a huge open polo field, horses with horseshoes on, lightening going off in the distance....but...... I wanted them to stop the game, but they were really mean, made fun of me and said NO. These were all bravado men (my kids 14, but he plays in adult leagues) there wasn't much I could do--I remember it was one of the longest, most horrible 30 minutes ever. I wanted to take the Patron and shake him for his stupidity (Patrons sponser and pay the players on the team and often have "god-like power and ego") I had such an migrane afterwards, I was a wreck. And we don't work w/that Patron anymore Member Since: 18 juillet 2007 Posts: 30 Comments: 26538

Mobile extended discussion... "Long term (friday through wednesday)...the weak tropical wave continues westward across the Gulf on Friday with deep tropical moisture over the forecast area reflected in high precipitable water values near two inches. An upper jet maximum dives out of the western Canadian provinces and into the northern plains through Saturday evolving into a longwave trough over the eastern states...with a surface low moving across the Great Lakes on Friday then evolving into a slow moving occluded system over Quebec on Sunday. While a surface ridge over the northern Gulf maintains a light onshore flow...a weakening front associated with the surface low slowly moves southward into the southeast states...eventually moving through the forecast area on Monday. The pattern supports staying with good chance to likely probability of precipitation through Sunday for the mainly daytime and early evening convection...then chance probability of precipitation for Monday as the weakening front moves through. Chance probability of precipitation continue for the remainder of the forecast as the front lingers near the coast and dissipates while a predominately light onshore flow resumes. Temperatures will be near seasonable levels through the period.".................. 50% chance of rain today...and tomorrow...60% on Saturday, in Mobile,AL.

You get some gorgeous waves up there, never been to your beaches, but have seen some gorgeous pictures of surfing -- the only thing that scares me about your homebeaches are the rip tides, your rips make ours look like childs play Member Since: 18 juillet 2007 Posts: 30 Comments: 26538

lol, yeah they say if you can surf the GOM you can surf anywhere....i love the east coast waves..they are so easy to ride..we have WAY too many close-outs!! yeah our beaches are awsome!! white sugar sands, even after gees lost count of how many storms we have had..lol Member Since: 3 juin 2008 Posts: 0 Comments: 1919

so nice to have a day off from working the barn --jumping out for a run, before that blob out there gets any closer, doesn't look like I am going to get a paddle in today (boohoo) but I'll take the rain in exchange. Got to get groceries today any way --so I guess it works, BBL Member Since: 18 juillet 2007 Posts: 30 Comments: 26538

caught it, it's the fuel prices making also adding to those juice prices. also there are less and less orange groves left anymore ( due to the insane building that went on) When we first moved here I could bike to an orange stand and get it cheap and muy fresco....now that's just a past memory Member Since: 18 juillet 2007 Posts: 30 Comments: 26538

Thank you regarding the word close outs. Sometimes here on the Gulf I loose all my confidence as a surfer --pearling after pearling --board just pitching --then I take a trip over to the other side and I'm like "I can surf, I can really surf...yoooo I can even walk the board" (longboarder) The power of the push in the Atlantic makes such a difference (even on those 2/3ft waves - which at 50 years old is a pleasure - less crash and burn)...eekkk am I that old....only in number NOT in spirit Member Since: 18 juillet 2007 Posts: 30 Comments: 26538
