The Atlantic is still alive it seems. This one looks like it could thread the needle and make it into the GOM, the first one to do that this year i think.

the current NHC track shows is weakening as it affects Latin America, but THEN strengthens and heads to the gulf! if it gets there is perfect breeding ground to become a Hurricane and make the first major US landfall this season. The Atlantic isn't dead yet!

Looks like we'll get Ida by next advisory based on satellite imagery. The circulation looks well defined and convection is very much persistant over the centre. It'll be interesting to see what recon find after completing the investigation.

NHC are uncertain on future track. It depends on just how strong 11L gets in the next 24hrs, which will effect how the depression responds to troughing which will ultimately lift 11L out of the current weak steering environment. Indeed, 11L has the potential to move into the Gulf which contains some warm, undisturbed tropical waters currently.

Indeed Cookie, and Ida is a little stronger than I though it would be- intensity is 50kts. Ida is rapidly intensifying, but it only has another 12-18hrs over water. Land interaction will soon begin to occur so any further intensity gains should be modest. Ida is forecast to survive it's treck over Nicaragua as a tropical depression and then slowly re-strengthen over the northwestern Caribbean. However, NHC mentions Ida could dissipate over Nicaragua, and this is even more likely if any significant shift westwards is made when Ida is over land.

Ida, though only a tropical storm, could be deadly. Around 10 inches of rain is possible for Nicaragua, which will cuase life threatening floods and mudslides. Looks like Ida may sadly be the first real killer of the Atlantic 2009 season.

Recon has completed a second pass and is now heading back to base. Intensity has been increased to 55kts, and an eye appears to be forming. I give Ida about a 50% chance of becoming a hurricane before landfall.

IDA becoming a Cat 1 before landfall isn't out of the question, plus its looking quite possible that IDA will make it intact to the gulf by Monday and regerate and possibly get stronger?

Ida will soon become classified by the NHC as a CAT1 within the next few hours, if not sooner given the Recon and Nicaragua government advisories. Inhibited moisture is all around to feed Ida looking at the Water Vapour images and nocturnal cooling will also play a part in explosive convection within the system at this stage.

dose it appear that ida has stalled a little?

2009AL11_4KMSRBDC_200911042245.jpg

i'd say slowed down but not quite stalled, this will favor further development, looks like we will have a Cat 1 shortly.

that looks very likely to me cookie, this storm has got potential, and all conditions are pefect for development in that area, also high pressure is building over florida over the weekend and a trough SW of the storm at this time will channel it in a Northerly direction, right into the area where development can and will occur.

This is definately a very interesting storm to watch.

NHC has now said that there is a possbility of IDA becoming a CAT 1 before its first landfall

only the other day i was dismissing the hurricane season as pretty much over. well that appears to have been a wrong call, with the arrival of Ida. could be a very interesting system, but also lethal in the short term as it makes landfall. question is, will it make it to the gulf, and then what. certainly one to watch like a hawk. I'm sure the southern us state authorities will be.

EDIT. Latest advisory suggests 70 mph sustained winds, and just shy of hurricane status

Just a quick post from me today thanks to Uni work!

Anyway microwave imagery shows Ida is tracking NNW/N now just onshore. The structure is showing steady weakening in line with what would be expected with that as well.

Track should continue northwards more or less in the next 48-72hrs at least. The models are uncertain further on from that but I'd fully expect a bend to the NE and probably a Florida, maybe even Cuba strike. The NHC for now are showing a broadly northerly track but fully expect that to show a kink/bend to the NE over the next 24hrs or so.

As for strength, should emerge as a very low end TS/TD but conditions aloft are actually very impressive in the western Caribbean and heat content is still very high indeed so the only question is what state will it be in after land track. It'll probably have a good 36-48hrs over the great conditions so hurricane status looks quite possible and I wouldn't even rule out a major hurricane either. Shear in the GOM may actually support this becoming stronger for a little bit as the outflow becomes enhanced. Eventually upper shear looks likely to increase as the upper trough digs down and thats why I suspect it should bend back and probably weaken, though exact timings are uncertain.

Interesting to get a hurricane in the WCAR in an El Nino year in November thats for sure!
