Remnants of Emily could redevelop; Muifa batters Okinawa; Central U.S. roasts

Tropical Storm Emily degraded into an open tropical wave yesterday afternoon, after Hurricane Hunters could no longer locate a center of circulation at the surface. Through the morning yesterday, the storm appeared to lose most of its strong thunderstorm activity on the north side, and mid-level circulation was broad (tropical cyclones need a tight, coherent circulation to maintain themselves). Soon after the Hurricane Hunters took a pass through the storm, the National Hurricane Center demoted Emily from a tropical storm to a remnant low, while continuing to stress the rainfall threat to Hispaniola and eastern Cuba. Today it appears the center of the remnants are located just north of eastern Cuba in the southern Bahamas, although thunderstorm activity continues across eastern Cuba. Hispaniola probably saw rain and thunderstorms again early this morning, the strongest of which were on the eastern side of the island. New thunderstorm activity is starting to develop in the southeast Bahamas. Given Wednesday's rain gauge analysis from CPC, Hispaniola probably saw at least an additional 5 inches of rain yesterday.

Environmental conditions remain pretty much the same as yesterday, but are expected to become more favorable for Emily's remnants, and redevelopment of the storm is possible. Circulation from the low to mid-levels is still broad and tilting to the east with height due to the lingering moderate westerly wind shear. However, this shear is expected to dissipate some over the next 24 hours, and signs of this are already present to the west of the remnants. The dry air that has been following the storm since its inception has dissipated, as well.

Forecast for Emily's Remnants
Interestingly, the models have come into better agreement on the forecast for former Emily now that it has lost its surface circulation and degenerated into a tropical wave. The ECMWF, which has come out ahead in this forecasting game so far, is optimistic today that Emily will redevelop. Other global models—GFS, CMC, and FIM—also redevelop the storm. Consensus on timing of redevelopment seems to be when the wave reaches the northern Bahamas in 24 to 48 hours. At 12Z (8am EDT), the high-resolution HWRF model run forecasted a track that was furthest to the west of all the models, scraping eastern Florida as it travels northwest. The most probable track and intensity forecast that I see at this point is north-northwest movement over the next 24 to 36 hours, at which point the system will take a fairly sharp turn to the northeast and out to sea. Without an already established, coherent circulation, it appears unlikely that if Emily is reborn it will intensify into anything more than a moderate tropical storm. However, there is some potential as the system moves out to see that it could gain some strength and develop hurricane-force winds before it transitions into an extra-tropical cyclone.

Typhoon Muifa passes to the south of Okinawa, heads into East China Sea

The center of Typhoon Muifa passed to the south of Okinawa earlier this morning (Eastern time) and it continues to batter the islands with high winds and torrential rain. Local radar estimate rainfall rates as high as 80 mm/hour (approx. 3 inches/hour) in the strongest rain bands. Kadena Air Force Base near the city of Okinawa has been reporting sustained winds of 47 mph with gusts up to 72 mph. Muifa is expected to turn northwest today as it enters the East China Sea as a category 1 on the Saffir-Simpson scale, and then intensify into a category 2 as it passes close to eastern China. This morning, the forecast is that Muifa will probably not make landfall anywhere as a typhoon.

South-Central U.S. continues to bake

The extreme heat continues again today after 269 high maximum and 250 high minimum temperature records were set yesterday, 19 and 29 of which were all-time records, respectively. 206 of yesterday's records were 110°F or higher. Yesterday, Reuters was reporting that Texas was one power plant shutdown away from rolling blackouts. The forecast today doesn't look any better. Heat index values up to 125° are forecast in eastern Texas and the Lower Mississippi Valley.

Particularly toasty heat index values from yesterday:

• Mobile, Alabama: 120°
• Arkadelphia, Arkansas: 121°
• Bay St. Louis, Mississippi: 121°
• Memphis, Tennessee: 122°

In any given year anything could happen. If the Blog had been active in 92, lots of folks would have been calling it a bust year until Andrew hit out of the box in latter August. I went through Andrew and could not tell you the names of any of the other storms that year because it did not matter after that. We just have to wait to see how patterns emerge from storm to storm before jumping to a general conclusion (other then educated or semi-educated guesses) as to what could happen.....One storm at a time.

Well it just started raining but it is coming from the west but it is coming from the west is it a wrap around...I do not know much just fascinated by the weather and oh yea i am in dania beach just south of ft lauderdale

It should also be pointed out again, that just like when Emily was near PR, the radar is showing us the echos at about 6500 feet near ex-Emily's center right now. That is showing us more of the mid-level circulation, not the surface.
Wind is North at west end....and south in Freeport.

Exactly where the radar shows the spin now too.

But yes I understand your point Levi.

I thinks its because hes Alaskan they trust him more, you know those Alaskans can smell rain in Russia from their houses.

Is that because it smells like Chernobyl?

Thanks for mentioning that, people always forget. How do you determine the height? Is there a basic rule of thumb or is it a formula? Saw another met say it was ~15,00ft.

How are you making this analysis? I'm not trying to be rude, I usually enjoy you're posts, but if you are going to say something like that you better back it up with more reasoning then stronger cyclones following upper steering currents.
It seems like the best in the business are saying the CONUS is favored for landfalls this year, but even they admit it's almost impossible to tell more than 2 weeks out.
What are you seeing different?


Well maybe its because they are expecting the current steering to change, but I don't see why it will...

Also, I'm really not that computer savvy, so I don't know all that HTML crap to be able to post the information I'm looking at. But I'm basing what I'm saying on the dominant steering patterns, they favor storms still avoiding Florida like more of recent years. You aren't my meteorology professor so I don't need to prove to you why, it would be too much trouble that I just don't feel like going through.

And remember, I never said I expect hurricanes to avoid the U.S. I said Florida has an elevated chance of avoiding hurricane landfalls again. I live in Florida so I focus on Florida weather.

Ultimately, nobody should be planning for hurricanes in Florida based on anything I say because I am not a professional, but an early student. So I don't want anyone thinking they can put hurricanes behind them because they live in Florida and I think Florida has a high chance of being avoided again this year.

In 2009, Phantom Regiment housed at my high school before going off to compete at the DCI Eastern Classic in Allentown. Being a huge Phantom fan, my assistant band director really wanted a picture with their drum major, Koji. He only saw it fitting if they'd reenact the famous drum major scene from their 2008 show (reenactment on right, finals scene on left).

Im tring really hard to see a North motion. I just dont see it. The last hour seems like a more West jog than North. Maybe been stairing at the old computer to long.


The convection that is flaring out to the west is giving ex-Emily the illusion that the "whole" system is moving west. It is still drifting north.

Hi Tigger, probably good you left when you did, not worth the risk. Glad your son is ok.


Hey Ocean...yeah...it was creepy...even at the points when i was only in to my knees, the waves started pounding and i was covered past my waist depth wise... like i said, we are use to the ocean and currents, i have an app on my phone for tides and such...and the waves came in angled from the south...they usually come in a little angled but these seemed more emphasized today...and strangest part was the tide seemed higher today, it was only 2 ft from the high tide drop off edge 3.5 hours before high tide...thanks btw for peewee's well wishes...he is ok, hurt his pride some lol...another note tho was a woman not too far with us got nailed on 5 diff parts of her body by jelly fish...ems actually called out on this one...

Looks like we have TD Emily. Interesting to say the least. Looking forward to following her development as she nears TS strength over the next day or so.
