ATL: BERYL - Post-Tropical

[Aric Dunn]

although convection may be trying to develop right now. not sure it will maintain. the upper low is still on top of and has not weakened much that I can tell.

Not at this time.

Savannah should get a good bit of rain out of Beryl. It'll stall south of there and wait to be picked up by an approaching trof. Plenty of time for well-needed rainfall across the southeast. As for what this means for the season - not much. Neither Alberto nor Beryl was formed from tropical waves. Mostly leftover frontal boundaries. Once these are out of the picture in a few weeks such development will cease and we'll see how the tropics look after then. I still think a sub-10 season is possible.

Why will these type of storms stop in a few weeks, can't frontal storms happen year round? I mean last year Bret, Cindy, Franklin, Rina and the storm discovered in post season analysis all have similar origins? I am young so I could be wrong, but I really thought that these could happen all year.

Strong cold fronts are hard to come by during the peak of hurricane season. Thus, tropical cyclones that originate from fronts are most likely early in the season (June/July) and late in the season (October/November).

Rina originated from a tropical wave, by the way.

Are you sure about Rina? I recall it breaking off from a front.

not till that upper low starts to weaken. some deep convection would help the process.

Looks like storms starting to wrap around center now?

From this afternoon's discussion of Beryl by Dr Jeff Masters.

The following post is NOT an official forecast and should not be used as such. It is just the opinion of the poster and may or may not be backed by sound meteorological data. It is NOT endorsed by any professional institution including storm2k.org. For Official Information please refer to the NHC and NWS products.

The counter-clockwise flow of air around an extremely intense ridge of high pressure that is bringing record heat to the Midwest this weekend is currently driving Beryl to the southwest, and this motion is likely continue until Beryl is very close to the Georgia/Northern Florida coast on Sunday night. As I explain in my Subtropical Storm Tutorial, a subtropical storm typically has a large, cloud free center of circulation, with very heavy thunderstorm activity in a band removed at least 100 miles from the center. The difference between a subtropical storm and a tropical storm is not that important as far as the winds they can generate, but tropical storms generate more rain. A key difference between tropical and subtropical storms is that tropical systems have the potential to quickly grow into hurricanes, while subtropical storms do not. Thus, we need not be concerned about Beryl intensifying to hurricane strength while it is still subtropical. If the storm manages to build a large amount of heavy thunderstorms near its center, these thunderstorms should be able to add enough heat and moisture to the atmosphere to turn Beryl into a tropical storm. This process will be aided as Beryl passes over the warmest waters of the Gulf Stream Saturday night and Sunday morning. But as Beryl makes its likely transition to a tropical storm on Sunday afternoon and evening as it approaches the coast, the storm will move off of the warmest Gulf Stream waters into waters that are cooler (25°, 77°F), and with with lower total heat content. This will limit the storm's potential to strengthen. The 11 am Saturday wind probability advisory from NHC gave Beryl just an 8% chance of becoming a hurricane. There is a lot of dry air surrounding Beryl, thanks to an upper-level low pressure system aloft, and this will keep rainfall amounts much lower that what we would expect if Beryl was a tropical storm. Thus, flooding due to heavy rains is probably not a huge concern with this storm, particularly since the Southeast U.S. coast is under moderate to extreme drought. The 2 - 4 inches of rain expected from Beryl will not be enough to bust the drought, since the Southeast U.S. is generally suffering a rainfall deficit of 8 - 12 inches (since October 1.) Heavy rains from Beryl are not likely to begin affecting coastal South Carolina, Georgia, and Northern Florida until Sunday.

As Aric pointed out earlier Beryl looks to be doing a cyclonic loop

[Hurricane Andrew]

Recon over 1 hour late?

[cycloneye]

It's been over one hour now the delay. Maybe,they takeoff from a closer base in Florida and that is why the delay?

[cycloneye]

Almost stationary at the moment.

[Aric Dunn]

The other thing is it will have to resume a wsw motion to get close the next forecast point. if it takes a SW track it will be south of it by a good deal being that its already south of the track now.

It appears the upper level cold low is beginning to cooperate is it is no longer elongated and completely stacked with the 500 mb, 700 mb, 850 mb, and surface heights.

[Hurricane Andrew]

Still nothin on TropicalAtlantic.

[Dave]

Waiting here.

IT still needs to weaken if you want to see any substantial strengthening.

At Fernandina Beach, Fl, the barometer has been holding steady just above 30" and the winds are freshing slightly from the north. There are no indications of an incoming storm as yet. We are quite a bit south west of Berly's position. SSTs are an unusually warm 77 deg here at the mouth of the St Mary's river where there is typically is a cold spot.

Local weather reports suggest 3 to 6 inches of rain beginning tomorrow morning with gusting winds to 50 MPH.

I believe that the lack of much high pressure to the north, meaning not much westerly component of low level steering, is a factor that may make for a slower track toward the SE US vs. the projection. Perhaps the models are assuming too high of a mean steering level currently, which is SWrly once up a ways. I'm still assuming it will eventually make it to the US as I expect a resumption toward the coast, but I suppose that's far from a guarantee, especially if a sig. W component of motion doesn't resume by this evening. I've seen it happen in the past. Let's see.

Curious to see the 2PM coordinates. It looks almost stationary since the last update.
But there is also more convection around the center and the eastern half of the storm.
