Ernesto hits the Yucatan with 85 mph winds
Ernesto is tropical storm again, after making landfall Tuesday night at 11 pm EDT just north of the Belize/Mexico border as a Category 1 hurricane with 85 mph winds. We have few good weather observations near the landfall location, though an automated weather station on Banco Chinchorro Island just off the coast of Mexico reported a minimum pressure of 979.4 mb. A personal weather station at the Margarita del Sol Costa Maya Resort recorded sustained winds of 42 mph, gusting to 49 mph, and a pressure of 988 mb in the west eyewall of Ernesto before the station failed. No other weather stations were in the eyewall, and we did not have a hurricane hunter aircraft in the storm at landfall to measure the winds, due to technical issues. Belize radar shows that Ernesto's eyewall has collapsed, but the storm has remained well-organized during its passage over the Yucatan Peninsula. Infrared satellite loops show that Ernesto's heavy thunderstorms are mainly affecting Mexico.

Forecast for Ernesto
Both radar and satellite loops show that Ernesto had a south of due west (260°) motion this morning, and it is no longer clear if the storm will re-emerge over the ocean on the west side of the Yucatan Peninsula. Even if Ernesto does move out over water again, it will be very close to the coast, limiting intensification potential. The official NHC forecast still calls for Ernesto to attain Category 1 hurricane strength over the Bay of Campeche. Ernesto's main threat will be heavy rainfall threat in the mountainous regions along its path through Mexico.
92L
A tropical wave in the Eastern Atlantic (Invest 92L) is disorganized, with satellite loops showing limited heavy thunderstorm activity and a modest amount of spin at mid-levels of the atmosphere. A large amount of dry air to the west and north of 92L is interfering with development, as seen on water vapor satellite loops. Wind shear is a moderate 10 - 20 knots. None of the reliable computer models develop 92L. The GFS model predicts 92L will reach the Lesser Antilles Islands on Saturday, but the other major models show a much slower motion with no threat to the islands for at least six days. In their 8 am Tropical Weather Outlook, NHC gave 92L a 30% of developing into a tropical cyclone by Friday morning.
A tropical wave predicted to move off the coast of Africa on Thursday night is predicted to develop by both the GFS and ECMWF models.

It was Weather Channel that brought it up. Hadn't really thought of it until the NHC brought it up in a Florence discussion. Besides, CSU and TSR came out with their August reports and are saying a reasonable 14 named. I don't think anymore that this season is going to be anywhere near as inactive as 2009 and 2006. August predictions are usually pretty accurate.
No, I was talking about TWC. Lol.
Ok. LOL
You really could make the argument that Chris had subtropical origins as well. That would put us with 4 system that have not origniated from the deep tropics and only two that have. With one becoming a hurricane. That's a pretty typical Nino season right there.
During the mid to late August period, the MJO looks favorable for some considerable MDR activity along with possible sleeper waves like 92L. This should produce around 3 systems from this pattern, possibly more if we have other places of origin. Things become very uncertain in the early September period as some long range models are showing a pretty good halt in activity. We'll see what happens with that as we get deeper into the month.
All in all, some serious analysis will be conducted at the end of this season to really see if the first four systems should be counted as true tropical development in the Atlantic. Numbers should coincide with a slightly above average season.
Maybe. With the bonus three that we had at the beginning, it's a reasonable prediction to say we will have 14. If that's the case, subtracting 3 would still put us right at normal. You are correct that this is no 2009 or 2006, so far. My point was that I didn't want people to start comparing this season with 2010 or 2005 just because of numbers.
Actually I have been downcasting this season because of El-Nino coming until 2 weeks ago when things looked like they were about to go off. Again he was talking about TWC. If you watch them sometimes you will see what we are talking about. I think they are worse that JFV sometimes.
Thats what we need more government to tell us what to do. Honestly i'm not trying to be rude but do we really need a nanny state to tell us every move to make? Let the kid go experience life its much better than video games
I still am sticking with what I've said since my first pre-season guess in January: 14-6-3

Last year had loads of non-tropical development, by this time we weren't even on our first hurricane where as this year we are on our second and a Hurricane landfall. Beryl was pretty dang close to hurricane status when it hit Florida too, so they're no where near as weak and meager as they where last year.
But we could still have a cat3 or 4 landing on the gulf coast this year.
You could be right on target.
what el nino? we keep switching from 0.4 to 0.6C we are a borderline warm neutral weak el nino. it wont be a weak el nino till late september early october so this season should still be above average. the atmosphere now represents neutral

True.
2011 was a crappy year. For someone who does not like the frontal systems in the Subtropical Atlantic, I got pretty irritated. Lol.
It's pretty safe to say, that the EPAC took all of our BIG storms last season...
Almost all of the EPAC storms were hurricanes in 2011
The atmosphere has more El Nino characteristics than neutral when it comes to pattern type and circulations throughout the globe. It's coming, believe me.
I said 14-7-4
Jeez, why not. The .gov seems to tax everything else. I guess freedom shouldn't include getting in your car and following a storms around. If you want to do that, pay the man.
WxGeekVA, more power to you! I spent a year in Colorado and that was enough for me...decided Californian earthquakes were more bearable than being near tornadoes and severe thunderstorms! I love thunderstorms, just not those severe ones!I prefer North Wales, just rains a lot...but no earthquakes, no tornadoes, no hurricanes LOL
2010 had some epic storms on our side though. Alex, Danielle, Earl, Igor, Julia, Karl, Tomas to name a few.
This run makes more sense.. Instead of going north into a ridge, it steers south of the ridge.
(sigh) So, that explains any errors in all our guestimates, lol. Blame it all on HAARP & chemtrails, right?

Just ask the people across the upper Mid West down to the TN Valley as lows could dip into the 50's and some upper 40's in the Applachian MTNS come this weekend.
Couldn't find specifics on Florida landfalling data with respect to the ENSO cycle, but this is a good paper explaining the effects on U.S. landfalling storms (although 14 years old).
The commerical ship fleet as well. They watch how storms move because it could impact a ship movement from Northwest Europe to the US. Or something like that.
