TS Emily: 215 Miles SSE Of San Juan, PR


Recommended Posts

Dave, Glad to hear it. You missed another 100 degree day yesterday. Emily is finally looking a little more organized so it may be deepening a bit. Most of the Hurricane models miss have the stomr missing the U.S. except the shallow and medium BAMS. I think that implies that if the storm stays weak Fl still is in the picture but the stronger the system gets the more likely it is to recurve. Still this early in the game, you can't rule out anything.

Thx Wes. Yeah I was laughing at the end of the evening show on the main stage, the cruise fun director showed us an accu wx radar map from 3 hours prior to that time the last days, no clue what he was talking about, LOL.

Im just glad we missed it, but at the same time was looking forward to seeing some good waves. good luck to the people of DR and Haiti it sounds like.

The humidity was so heavy last night around 11pm. Wow, you could have cut it with a knife, it was brutal outside on the deck

I have no idea what to think. Now there are outflow boundaries shooting out the northwestern quad.

Don't think, just present your clients with a hurricane plowing thru Homestead. You'll be popular.

Edit: I'm the anti-Typhoon Tip, I get my posts very near the top of the page everytime. Thanks mods.

Good thing I only have to send one forecast a day. I think I'd have amended my forecast about 3 different times in the last 3 hours if I was actually operational.

There's an utter absence of organized rain bands, likely due to the suppression by dry air. The convective pattern is not organized at all and not indicative of intensification IMO. The bursting of convection in sheared storms hardly ever results in anything other than temporary intensification in my experience.

With such heavy and widespread convection, that LLC is going to tighten like a screw in a wall.

The sat appearance is improving rapidly. If the center is indeed steady now under the deep convection would expect pressure to drop and winds to be on the increase shortly.

It looks like the low-mid level flow has slowed some, as evidenced by the slowdown in forward speed from yesterday. This could be alleviating the shear some, as the northwesterly flow at 300 mb is still evident on the PR sounding this morning. The realignment of the center closer to the convection is a positive short-term sign, as it's allowed the storm to hold its own. I'm skeptical if this is a beginning of a longer-term intensification trend though, given the continued presence of the northwesterly flow aloft and the strengthening of the 850-200 mb shear over the next 24-36 hours by SHIPS. Given current trends, this will probably at least hold its own until it interacts with Hispaniola. What happens after that is highly uncertain, but the shear does improve after the island crossings.

If there is any good news regarding this cyclone, we will see another G-IV mission tomorrow. Any help to guidance will go along way...

As has been predicted by the GFS ensenble mean for a number of days, the NAO has fallen to near -2 and may fall a bit further. This represents the lowest daily NAO reading since 12/1/10. The pattern associated with this should help to protect the US east coast from a direct/nongrazing hurricane hit. Also, I'm giving only a small shot at a direct TS hit from off the Atlantic north of FL. Hitting FL as a TS would be a better bet a la Ernesto of 2006 when the NAO was also near -2. However, it staying completely offshore the east coast seems to be the best bet as of now.

FWIW, the ADT has a known high bias in sheared situations.

So Jorge is bullish, CUMet is bearish, and I have no clue. Good thing we have a consensus.

Moderately bullish... I don't think we see more than a high end TS before land interaction... more bullish in the W Atl, but still too early for that.

I'd probably go with something around steady-state around 35-40 kt, with some short-term fluctuations typical of sheared storms. Despite the impressive wind readings and the lower pressure on the current pass, I'm still not convinced this is a long-term intensification. It's certainly within the realm of possibility that it is, but then again we've been fooled by this before. I don't think this will die before Hispaniola though.
