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!

wrong the bermuda high coupled with the azores high is setting up a lot further west this year protecting the east coast and increasing the threat to the yucatan and middle texas coasts....StormTop

98L Update
25knots (30mph)
1011mbar
Convection has increase this morning.
Poorly organized.
Over 20-30knots of shear, shear tendency (steady)(not decresing or increasing)

U people are crazy i mean u really need to think about what happens in Aus and Sep I mean the wind shear lowers and June and July are peak mounths for Dust so less Dust also there is areas of very warm water so I really really Dough This is going to be a inactive season

Is anyone looking at the model (CMC, GFS, NOGAPS) runs for the Bermuda high? It's parking it waaay southwest, and -weakening- it, from like 1030-1040mb to, like, 1016mb. Anyone have comments on what-all this might mean?

I'm afraid the Bermuda High might be parking a little further south and west which sets up almost identical to 2004 when Florida got smacked from both sides.

agreed littefish, Shear will die down when Emilie moves on. She's hanging too close to land to develop into anything major. She's also pushed that low pressure area associated with the tropical wave into the gulf a little more. We'll see what happens with 98L once Emilie leaves, if she don't shear 98L to death 1st.

It will become more favorable for development as we get into August. The wind shear will not last all season long. The patterns will change and when they do, expect some serious action. Keep in mind, there have been several healthy waves this season that were just torn apart by the shear. We did not have this shear last year which is part of the reason last June and July were crazy.

African dust and wind shear, this year's season in a nutshell so far.

When is that wind shear gonna die down?? I still think 98L will develop, but that wind shear is still quite strong. We've had heavy wind shear daily for several weeks it seems throughout Gulf and Caribbean... If wind shear doesn't die down, nothing can develop. Guess that's good for some:) Not for me, a storm junkie...

E. 24/1730Z TO 25/0000Z
F. SFC TO 10,000 FT
I figured it would gain convection a little through the night, seems to be sucking off one of Emilie's feeder bands at the moment. By late afternoon early evening it will probibly be lacking in convection again.

Morning all. Looks like, with the exception of 98L things are pretty quite out there. THe only model picking up on anything in the next few days is the Canadian, but it has been very aggressive all season so don't think it can really be considered too much until at least one other model comes in line.

Anywho, I have got the day off, but will have to work this weekend, so I am going u=out to get some stuff done in the yard.

Ya'll have a great day

mr...enjoy your day......yeah..old at 28...i'd say...wait til you hit 40...then see how you feel..but everyone says to me...wait til you hit 50..then you'll really feel old....and i'm sure it goes on and on... the only upside to growing old is that it beats the alternative

I might have thought that BOC wind speed was a thunderstorm downdraft but the speeds have picked up to 20 knots for over an hour. Maybe they will send a recon.

here's the forcast for pr for the next few days
TODAY AND TONIGHT...LIMITED MOISTURE ACROSS THE AREA WILL COMBINE
WITH DIURNAL AND LOCAL TERRAIN EFFECTS TO PRODUCE SOME SHOWERS AN
ONE OR TWO ISOLATED THUNDERSTORMS ACROSS PARTS OF THE INTERIOR AND
WEST SECTIONS OF THE ISLAND. SOME OF THE SHOWER ACTIVITY WILL BE
LOCALLY HEAVY AT TIMES AND MAY PRODUCE MINOR FLOODING PROBLEMS
MAINLY IN LOW LYING AND POORLY DRAINED AREAS.

A WEAK TROPICAL WAVE WILL MOVE ACROSS THE AREA TODAY. THIS WILL
SERVE TO ENHANCE SHOWERS WHICH ARE ABLE TO FORM IN THE RELATIVELY
DRY ENVIRONMENT AND INCREASE WINDS IN THE AREA. THEREFORE MARINERS
SHOULD EXERCISE CAUTION DUE TO INCREASING WINDS AND SEAS.

.DAYS TWO THROUGH SEVEN...
THE NEXT ACTIVE TROPICAL WAVE WILL ENTER THE EASTERN CARIBBEAN
WEDNESDAY NIGHT INTO THURSDAY. THIS WILL BRING A SIGNIFICANT
INCREASE IN MOISTURE AND A WETTER WEATHER PATTERN TO THE LOCAL AREA
BY THE END OF THE WEEK. AS A RESULT...THE CHANCE FOR LOCALLY HEAVY
RAINFALL AND URBAN AND SMALL STREAM FLOODING WILL BE ON THE
INCREASE. ALSO...WINDS AND SEAS ACROSS THE REGIONAL WATERS WILL BE
ON THE INCREASE. MARINERS SHOULD BE ALERT TO THESE POSSIBLE
HAZARDOUS CONDITIONS.

Hey Franck,

I have to point out that for many years, the Louisiana coastline has been destroyed by the Corps of Engineers intentially forcing the Miss Riv down one unnatural channel for the sake of shipping interests (for the entire US) The remaining coastline is polluted and degraded by coastal oil drilling (which has at times supplied up to 40% of the nation's oil) Our bottom-land forests here were denuded by national logging interests after the civil war, and our swamps and marshes drained to farm soy beans for the nation.

We are, by the way, Americans here in New Orleans. Our taxes helped bail out airlines and compensate victims after 9/11. Our little towns and parishes sent fire trucks to Manhattan. Go a little further back in history and you will find millions of examples of hard-working Louisianians giving deeply of themselves for national causes.

If the Federal government had honored promises of wetlands restoration and put a tiny fraction of the amount being currently spent on foreign wars into stablizing and repairing the natural systems that have protected coastal LA from storms for centuries, then Katrina would not have had the impact it did.

Yeah, not sure if there were intentional motives there. Katrina didn't really hit New Orleans at all, but it was such a monster
just grazing the city was enough. The levee thing can be viewed as a big protective chain around the city. It really just took the break of a single link to destroy it. But everybody concerned knew all that for decades. Now the big easy is just a hole where American taxpayer dollars are poured.

check out this article i found about katrina

A warning to the scientists, who were behind the systematic reduction wind speeds of Hurricane Katrina thru the media outlets as it approached the coastline, your credibility will be lost, if the same trend of behavior continues. More would have left affected areas if they knew the true wind speeds of 200215 mph and eye pressure was below 900mb at its peak. That storm turned away from New Orleans only in the last few hours with 30+ ft storm surges and monstrous waves on top.

105AM CDT

TROPICAL WAVE IS ALONG 99W S OF 21N MOVING WEST 5-10 KT.
THIS WAVE IS INTERACTING WITH A BROAD UPPER RIDGE OVER MEXICO
TO PRODUCE DISORGANIZED SHOWERS AND TSTMS ACROSS S MEXICO AND
THE SW GULF. UPPER-LEVEL WINDS ARE EXPECTED TO BECOME A LITTLE
MORE FAVORABLE FOR DEVELOPMENT DURING THE NEXT DAY OR TWO AS THE
WAVE MOVES SLOWLY.

Not sold on the idea it's moving west... But it does look more like it is going to make landfall early Tuesday south of Brownsville as a wave... Sat pics are pretty anemic for this time of night. No imminant development. If it does make TD status, it'll be Tuesday just before landfall but I highly doubt NHC will classify it at that time.

See yall tomorrow..

It is dead (ok, I didn't leave lol!) but that's such a good thing after last year,. My sister lives in NOLA, and her whole life is still farked after Katrina. Her best friend was going to go pick up my sister so they could go to yoga together, parked her car, and promptly fell into an open manhole and into the NOLA sewer! She;s on major antibiotics for weeks. I can't imagine living there now. So a quiet season, if boring, at least hopefully won';t give us another Katrina!
