Dr. Jeff Masters' WunderBlog

A Tale of Two Invests
Posted by: Dr. Jeff Masters, 12:17 GMT le 04 juillet 2010 +2
Good morning, everybody, Dr. Rob Carver filling in for Jeff on Independence Day.

Currently, NHC is monitoring two different areas for possible tropical cyclone development. Invest 95L is about 125 miles west-southwest of the mouth of the Mississippi and it doesn't have much thunderstorm activity associated with it. Dry air from the north and strong wind shear have weakened it considerably from yesterday, and NHC believes it has a 10% chance of becoming a tropical cyclone before the feature makes landfall.

Invest 96L is in the western Caribbean sea and bears watching closely. Earlier in the morning, the convection was all on the east side of the circulation center, but thunderstorms have developed on the southwest side. According to the CIMMS wind shear analysis, 96L is on the outskirts of a low wind shear region just east of the Yucatan peninsula. It's also over warm SST's (>29 deg C), so it could intensify. NHC gives it a 20% chance of becoming a tropical cyclone in the next 48 hours. Computer models have 96L going through the Yucatan Channel then turning left and making landfall somewhere near the Rio Grande.

Next Update
My next post will be sometime Monday afternoon/evening. If the situation changes significantly before then, I'll make a new post. In any event, enjoy the holidays...

TN then people do not know the full criteria of a tropical system


I just had a downpour associated with the circulation offshore of Tampa with 40mph winds gusts and it felt tropical, should that area be named too?

MH09, if they do upgrade it.. when would you expect a renumber?
I don't expect a renumber from 95L, but if we do get one it will be as it makes landfall.

NHC apparently thinks its tropical and has a chance, they bumped it up to Red alert. They even said '60% chance of becoming a tropical cyclone'

but in the end I go with the NHC, but it is pretty obvious that at times they can be inconsistent

last year was a fantastic example; they named Grace out in the middle of nowhere but did not name either 90L or the system by NJ

We've had well over an inch here. We have had very TROPICAL type rains. Very heavy, with little lightning.


Over here in Mobile we only had one little shower very early this morning @ about 5 am. It's been cloudy all day off and on, but that's been it.

If they do upgrade it, they better do it within the hour. This is about to make landfall. 96L is also increasing in organization.

WOW, Pat, that was one hell of a feeder band from Bonnie. Do you have your sutters on, just in case? Since the NHc faiiled to nail this one. Isn't this gonna catch all of the NOLA citizens off guard? Not to mention the oil spill.


WaS just a feeder squall..

Dead calm now.

WOW! I left with a 0% and come back and find a 60%? WTH? I guess it detached itself from that ole' front.. Still probably won't get renumbered, convection is very weak.

Im so glad that most of you bloggers dont work at the NHC..those people know more about storms than some of you ever will and to criticize them for not naming 95L which is nothing but thunderstorms with gale winds..every storm that hits the GOM is NOT a tropical cyclone..

This is one reason why you never turn your back on a system that is in your backyard and you will never hear me say a system is dead until the threat is 0 even if it's not upgraded the effects will still be the same.

I agree that the public has a right to know.. especially if their cars are not parked on high ground or at least the Neutral Ground... ;)
but I also think some people might panic if they upgrade it... Katrina PTSD and all.. just MHO

96L is still going to be the stronger of the 2 systems IMO


I am really not sure anymore whether 95L is attached to the front or not, the latest maps say it is, I can't tell

Either way the NHC I feel was right in the first place, this sudden jump to 60% is puzzling to me

funny cuz I just had a similar thunderstorm come through my street here in St Pete in association with that spin off the coast of Tampa

Should that be named too?

Yes i guess 3 maps was wrong......LOOK at this Graphic......you can easily see the Front in question......if 95L is at the very end of the front and NO one cannot say that is not the case.....then at what point can 95L be detached.....i can happen very quickly as it shows in this graphic i do believe.....
