Adieu to Danny

Posted by: Dr. Jeff Masters, 09:50 GMT le 29 août 2009

Hi, Dr. Rob Carver filling in for Dr. Masters. With the 5AM EST update, NHC has discontinued issuing the tropical storm watches and will no longer issue any updates about the storm. Danny has gone extratropical and has merged with a frontal low off the Carolina coast. The most recent aircraft reconnaissance flight was unable to find a cyclonic circulation or tropical storm force winds in the remnants of Danny.

That isn't to say that Danny's remnants don't pose an element of risk for the East Coast. High surf from large swells is expected along the East Coast. New England can expect to see a lot of rain as Denny's remnants fly by.

Invest 94L

Invest 94L is still out near South America, but it's convective activity seems to be cycling down right now. The global models (GFS and GEM) do pull 94L (to be precise, a feature that could be 94L) north of the Lesser Antilles. Given how the GFDL has performed with other Invests this season, I can wait a day or so before they run the GFDL for this storm.

East Pacific and elsewhere

For those of you wanting to look at tropical storms, Jimena has just formed in the Eastern Pacific basin. The track uncertainty is fairly large, so I'll be keeping an eye on this storm to see if it will impact Mexico or the American Southwest. In the Western Pacific, Tropical Storm Krovahn looks like it will be grazing the Japanese coastline just east of Tokyo Bay.

I'll give Invest94L a chance to see the Sun and then I'll update this entry.

Update:1545 EDT

G'afternoon everybody, Invest94L has perked up a little since this's morning blog entry. In my judgment, the extent and peak magnitude of convection has increased, and scatterometer data shows that Invest94L has a weak cyclonic circulation. Here's the 9Z ascending pass:

Quickscat Pass over Invest94L

Figure 1Ascending Quikscat pass centered over Invest94L at 9Z Aug 29 2009.

There will be a big update tonight after the 00Z model cycle data comes in.

Latest satellite loops show this is about to develop soon enough. Convergence is pretty good as well as divergence. This invest looks more organized and the surface low on the Quickscat looks closed and defined. I believe that since there are signs the banding is improving that it will only be hours before we get centralized convection going. Already showing cold cloud tops on the northern side as well as the southern side of the circulation. Also does not look elongated, but stacked there is no more convection moving sw when the low lags behind. I have to go to bed now, but in the morning I will give everyone my thoughts in my blog. Good night. Member Since: 21 octobre 2008 Posts: 215 Comments: 3159

Maybe, one of you can do it for me. Is the bouy at 41041, the preassure is dropping, the wind has increase fr the nne, the llc is almost south of the bouy

1780. TheDawnAwakening 04:38 GMT le 30 août 2009
Also banding and outflow are very good as well as outflow channels developing on the south and north sides. This invest has ventilation and invests don't have ventilation without something happening in the next 6 hours. How long did it take Jimena to do what she did?

Thank you tornadodude. My dauther tried to help me but she couldn't either. That bouy is almost 4 degrees fr the llc. For the next hour without imagen do to blackout, it is a good guide to know if it continue improving. Sorry for my english, I know I'm a disaster. lol
