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°

Emily mess is going nowhere fast tonight... IMO a drift towards the WNW is possible in the near future.

Our guide (real estate lady..lol) took us over to an area near the shore and told us how high the water had come up on a little roadway during one of the hurricanes. I would be scared living on an island during a big cane.
Storm surge from Ivan washed over all except the very NE corner of the island. I am not really afraid of that living on an island.

Yeah, I drove from Broward to Volusia today.
Much better driving north than driving south last night! Taking my life in my hands on the 5-lane highway from West Palm Beach to Fort Lauderdale.
Good Grief! I'm done.
Cannot imagine doing that in torrential rain.
Anyway, night all. Don't let Emily drive you nuts.

From the Insurance Journal (link to entire article below:


Key climate factors predicted in May continue to support an active season. These include: the tropical multi-decadal signal, which since 1995 has brought favorable ocean and atmospheric conditions, leading to more active seasons; exceptionally warm Atlantic Ocean temperatures (the third warmest on record); and the possible redevelopment of La Niña. Reduced vertical wind shear and lower air pressure across the tropical Atlantic also favor an active season.

Based on these conditions and on climate model forecasts, the confidence for an above-normal season has increased from 65 percent in May to 85 percent. Also, the expected number of named storms has increased from 12-18 in May to 14-19, and the expected number of hurricanes has increased from 6-10 in May to 7-10.

This has probably been posted before, but what the heck.
The NHC discussions, like a good book, can be read more than once!

ATLANTIC OCEAN...
THE CONVECTION ASSOCIATED TO THE REMNANT LOW PRESSURE SYSTEM OF EMILY IS AFFECTING THE ATLC WATERS N OF CUBA AND W OF THE BAHAMAS S OF 25N BETWEEN 73W-78W.
SCATTERED HEAVY SHOWERS AND THUNDERSTORMS ROAM THIS AREA....

ALSO...A SURFACE TROUGH ASSOCIATED TO THIS SYSTEM IS ANALYZED FROM 28N74W TO THE LOW LEVEL CENTER NEAR 23N78W INTO THE CARIBBEAN ACROSS CENTRAL CUBA. COMPUTER MODELS SUGGEST THIS AREA OF CONVECTION WILL CONTINUE TO MOVE NW SPREADING OVER THE WATERS NEAR THE NW BAHAMAS AND EASTERN FLORIDA SEABOARD OVER THE NEXT 24-36 HOURS.

GEOMAGNETIC STORM IN PROGRESS: A major geomagnetic storm is in progress following the impact of a CME on August 5th around 1800 UT. Sky watchers at all latitudes should be alert for auroras after nightfall. Tip: the best hours for aurora sightings are usually around local midnight. Aurora alerts: text, voice.

Reports of Northern Lights are coming in from many European countries including Germany, Denmark, Scotland and the Netherlands.

Analysts at the Goddard Space Weather Lab say that the CME impact may have strongly compressed Earth's magnetic field, directly exposing satellites in geosynchronous orbit to solar wind plasma. Stay tuned for updates on this aspect of the storm.

The arriving CME left the sun on August 4th, propelled by an M9.3-category eruption in the magnetic canopy of sunspot 1261. Click on the image to view a movie of the expanding cloud recorded by the Solar and Heliospheric Observatory:
