More heat; Gulf of Mexico disturbance
The heat was unrelenting yesterday across the Southwest U.S., where most of California and Arizona set new high temperature records. The 99 degrees in downtown Los Angeles beat the old record of 96 set in 1960, and the suburb of Woodland Hills hit a record 119. All the cities in California's Central Valley set records: 109 degrees in Sacramento, 111 in Redding, and 112 in Red Bluff, Stockton and Modesto. San Francisco's 87 degrees easily beat the record of 81 for the date, set back in 1917.
In Phoenix, this morning's low temperature was 97 degrees, which broke the all-time record for highest low temperature ever recorded in that city (96, set on Jul 15, 2003). Tucson's low of 89 Saturday morning was its highest low temperature in recorded history, as well. The temperature topped out at record 116 in Phoenix yesterday, and 121 in nearby Gila Bend.
Tropical update
An area of disturbed weather continues over the southwestern Gulf of Mexico. Wind shear is over 20 knots in this region, which is too high to allow development today. Both the GFS and NOGAPS models are forecasting this shear to be 15 knots or higher over the next few days, and usually one needs wind shear to fall to the 10-15 knot range for development. However, the NHC is playing it cautiously and has put a Hunter airplane on call for Monday, if needed. I'll be surprised if this flight happens.

Enjoy another quiet weekend in the tropics, everyone!

June and July, is left for old cold fronts, upper level lows and disturbances from off central america, like any normal year.
When is the plane scheduled for BOC? Any thoughts on this disturbance?
Monday. And it as a chance to develop, if it stays over water and wind shear decreases.
the tropics is full of suprises.

Well, I got to work only to discover NHC canceled us for today and tonight. We still have possible tasking into the Bay of Campeche tomorrow.
You can get first hand from him. And check out his pictures from Beryl and others.
Remember the NHC loves to say "Upper level Winds are not conducive for developemnt"
So i'm holding onto the NHC....but 98L cloud tops have warmed.
but still at 1009 mbar, 25knots (30mph)
456 dos that mean it is geting stornger as wel talk?
So you are telling me NOAA is totally wrong? The maps I looked at showed the total opposite of what you an SJ are claiming. Detail or not, the conclusion can't be THAT far off. Sure, maybe in spots here and there it may be warmer. Then again in spots its cooler. Overall everything I have seen shows its cooler.
Even the anomalies show the water is right where it should be in the areas you describe. Heck, the east coast was even cooler than normal for a while. Yes, I know this doesn't compare them to last year alone, but the point is the SST's are not as hot as some are making them out to be. Turtle had a blog describing the warm water in the northern Atlantic. Pretty interesting.
Even in the maps that SJ has in his blog, the east coast looks cooler over all.
I just think too much is being made of SST's right now being "warmer".
Warm Cloudtops-weak storm
In other words 98L has decrease in convection.
why are we comparing 2005 SST's to 2006 SST's, we all know 2006 will not repeat 2005.
Occured in the older blog before this one.
I agree with you about the comparisons. I just think too much is being made of the SST's. I don't see them as warm as others here.
this sucks i want a damn hurricane, BOOO mother nature, BOOOO
there is one in the eastern pacfic
A tad off topic, but relevant to the build up on our coastal areas at risk for hurricanes:
Too Many People on the Shore
as rainfall becomes more variable, combined with the already expanding Saharan desert (as a result of overgrazing and other factors), will added dust prevent more storms from forming, even though water temperatures may be higher? Dr. Masters, have analyses of tropical storms (their frequency and their intensity) included Saharan dust coverage or density as a covariate?
This is the chart from yesterday.
This is last years chart for the Gulf.
Think I saw a model run form this into a storm.
The most alarming assault on our way of life comes at the hands of powerful interests in Washington and Columbia, who want to open S.C. coastal waters to oil and gas drilling and exploration.
But the crowds keep coming. Some 500,000 new residents will move to our coast in the next 30 years. More than 30,000 new homes are in some stage of planning, permitting, or construction in the tri-county area alone. Where will those people live, work, and recreate, and what impact will they have on this fragile coastal ecosystem?
The biggest effect would come from the people brought to the area by that "alarming attack" by the interests of the rest of the country.
If they changed the title of the article to "Too Many People" and left it at that I'd be happier. :(
LOL!
Yeah, I saw your charts before you posted them. Mentioned I compared them in SJ's blog. Noticed you left the east coast out. :) Gulf looks slightly warmer according to your charts. East coast does not. Noticed a site with more updated anomaly info. Didn't realize the dating in the one I posted previously. Little warmer overall, but again these compare to the climate norms, not last year. Here you can find anomalies for both years. 2005 looked warmer over all.
Guess its a matter of perspective. Believe the sites you want, but I will stick with NOAA on this one.
Also, keep in mind that just because a CAT 5 crossed the waters with those temps before, DOES NOT mean it will happen this time. As said on here before, SST's are not the only factor in storm strength.
