quote:Forecasting Emily
Model uncertainty is still high for forecasting Emily's track. The 00Z CMC and NOGAPS global models keep Emily on a western track, before recurving to make landfall on the western coast of Florida. The 00Z HWRF and GFDL dynamic
hurricane models both have Emily approaching the eastern coast of Florida, but recurving sharply to the northeast before making landfall. However, the premier global models, GFS and ECMWF, suggest that forecasters should be very cautious.
The 12Z ECMWF did not get a good representation of Emily in its starting conditions, so the forecast Emily did not gain strength and drifted westwards, missing Hispanola. The 00Z GFS does not have any forecast features that could be reasonably associated with Emily in my judgement. From what I can tell, the GFS moves Emily's circulation over Hispanola and Emily then never has a chance to organize. This is disconcerting since the previous 4 runs of the GFS had produced a reasonably robust tropical cyclone with winds near or just exceeding hurricane strength.
Even though the tracks produced by these models are different in their long-term outlooks, they all suggest that Emily will pass by Hispanola close enough for that island's mountains to impact the storm's winds and thus dampen any intensification. However, the 00Z NAM model does not bring Emily near the island, and keeps it moving westwards into the Caribbean sea as a well-organized storm. This, combined with the widely different solutions discussed previously, suggests that people across the Caribbean and living along the Gulf coast should keep an eye on this storm for the next several days.
I would prefer to make an intensity forecast for Emily after it has cleared the island of Hispanola and it's tall mountains. Many storms have weakened considerably after passing by there, and some have dissipated (TS Cindy in 1993, for example).
In light of this uncertainty, the NHC forecast hasn't changed that much. Emily is forecast to turn towards the northwest, making landfall somewhere in southeastern Florida on Saturday as a weak hurricane. (5AM EDT update NHC has adjusted their forecast to the east, so Emily does not make landfall in the next 5 days. Also, Emily does not reach hurricane strength in this forecast.) Tropical storm warnings have been issued for Puerto Rico and the Dominican Republic. A tropical storm watch has been issued for Haiti.

Erg onduidelijk wat Emily gaat doen...quote:Emily eyes for Haïti
ROUSEAU, Dominica — Tropical Storm Emily was expected to bring heavy rain Tuesday to Puerto Rico after crossing the northeast Caribbean sea on a track that would take it near Haiti within 24 hours.
The storm was expected to bring up to 4 inches of rain to the Leeward and Windward islands and 6 inches to Puerto Rico and the Dominican Republic, enough to cause flash floods and mud slides in areas that have already seen heavy rainfall, the U.S. National Hurricane Center said.
The Weather Channel's hurricane expert Dr. Rick Knabb reported that the storm would likely cross over the mountains of Puerto Rico, which could weaken it.
Haiti and the Dominican Republic were at risk for heavy rains and mudslides, The Weather Channel said.
As the storm passed near Dominica overnight, a weather official urged people to hunker down.
"We are just advising everyone to stay put, stay alert," Senior Acting Meteorological Officer Cheryl Etienne Lebanc said on the state-owned radio station. "Now, might not be the time to be venturing out.

quote:'Eugene' strengthens into major hurricane
Hurricane Eugene strengthened into a major category three storm far off the Pacific coast of Mexico on late Tuesday evening, forecasters said. There is no threat to land.
Forecasters at the U.S. National Hurricane Center (NHC) have been following the weather system since Wednesday last week when it emerged as an area of disturbed weather several hundred miles (kilometers) south of the coast of El Salvador and Guatemala. It rapidly became better organized on Saturday and developed into a tropical storm on Sunday morning, before becoming a hurricane on Monday afternoon.
“Eugene continues to strengthen. Since the last advisory deep convection has increased in intensity and coverage and become more symmetric around the eye,” NHC hurricane specialist John Cangialosi said on Tuesday evening. “Dvorak classifications were 90 knots (103 miles/166 kilometres per hour) at 0000Z, but given the improvement in convective organization since then the initial wind speed is set at 100 knots (115 miles/185 kilometres per hour), in agreement with the latest ADT satellite intensity estimates. This makes Eugene a major hurricane, the third of the 2011 Eastern Pacific hurricane season.”
As of 2 a.m. PDT (0900 GMT) on Wednesday, the center of Eugene was located about 570 miles (915 kilometers) south-southwest of the southern tip of the Baja California peninsula in Mexico. It is moving toward the west-northwest at a speed of about 14 miles (22 kilometres) per hour, keeping it far from land.
Maximum sustained winds of Eugene are near 115 miles (185 kilometres) per hour, with higher gusts, making it a category three hurricane on the five-step Saffir-Simpson scale of intensity. The storm is not expected to become a category four hurricane.
“Eugene is moving over slowly cooling sea surface temperatures, and the hurricane is likely near peak intensity,” NHC senior hurricane specialist Jack Beven said on early Wednesday morning. “The new intensity forecast calls for a little strengthening this morning followed by a steady weakening over colder waters, with Eugene expected to weaken to a tropical storm in about 60 to 72 hours, to a tropical depression in about 96 hours, and to a remnant low in about 120 hours.”
Eugene is the fifth named storm of the 2011 Eastern Pacific hurricane season, following Hurricane Dora which formed off the Pacific coast of Mexico earlier this month. As the system stayed far enough from land, Dora caused no damage or casualties.
According to figures released in May, NOAA’s Climate Prediction Center is expecting a below normal hurricane season in the Eastern Pacific this year. The outlook calls for 9 to 15 named storms, with five to eight becoming hurricanes and one to three expected to become a major hurricane (category 3 or higher).
An average Eastern Pacific hurricane season produces 15 to 16 named storms, with eight to nine becoming hurricanes and four becoming major hurricanes. The Eastern Pacific hurricane season runs from May 1 through November 30, with peak activity from July through September.

Dit gaat dus een druk draadje worden, waarschijnlijk..quote:Hurricane Season Is Looking More Serious
On average, 11 named storms strike the Atlantic basin each year, six of which become hurricanes and two major hurricanes with winds exceeding 111 miles an hour. In May, the National Oceanic and Atmospheric Administration said there was a 65 percent chance that the 2011 hurricane season, which began on June 1, would be above average. It predicted 12 to 18 named storms and six to 10 hurricanes.
With the bulk of storm activity normally in August, September and October, the agency has updated its 2011 hurricane outlook: on Thursday, it said that there is now an 85 percent chance of above-average hurricane activity. Predicted storm numbers have been raised to 14 to 19 named storms, seven to 10 hurricanes and as many as five major hurricanes.
quote:Muifa veroorzaakt dijkdoorbraak bij chemische fabriek
Een tropische storm in het noordoosten van China heeft maandag een gat geslagen in een dijk rond een chemische fabriek. Het leger is ingezet om een milieuramp te voorkomen. Dat meldden Chinese staatsmedia.
De fabriek ligt bij Dalian, ten oosten van de hoofdstad Peking. Door de zware storm Muifa ontstonden tot 20 meter hoge golven, die gaten in de dijk sloegen. Omwonenden zijn geëvacueerd.
Vanwege het naderende noodweer had China eerder al ongeveer een half miljoen mensen geëvacueerd. Voor de oostkust werden meer dan tien vissersboten met circa 200 bemanningsleden vermist. Muifa komt vermoedelijk later maandag bij Dalian aan land.
Eerst zienquote:Orkaanseizoen heviger dan verwacht
Het orkaanseizoen in de Atlantische Oceaan wordt dit jaar heviger dan verwacht. Vooral tegen eind oktober dreigen frequentere en intensievere stormen, voorspelt de Amerikaanse Dienst voor Weer en Oceanografie (NOAA).
Verwacht wordt nu dat er veertien tot negentien stormen met windsnelheden van meer dan 62 kilometer per uur zullen komen - stormen dus die sterk genoeg zijn om een naam te krijgen. Zeven tot tien ervan kunnen orkanen worden, drie tot vijf daarvan orkanen van de categorie 3, 4 of 5. In mei had de NOAA twaalf tot achttien met naam genoemde stormen voorspeld en zes tot tien orkanen.
Volgens de gegevens staat daarmee een boven het gemiddelde actief orkaanseizoen voor de boeg - onder andere begunstigd door buitengewoon warme oceaantemperaturen. Het gemiddelde ligt volgens de NOAA bij elf stormen met namen en zes orkanen. Het Atlantische orkaanseizoen begint telkens op 1 juni en eindigt op 30 november. (belga/sam)

quote:Doden bij tropische storm Noord-Korea
(Novum/AP) - SEOUL - De tropische storm Muifa heeft dinsdag in Noord-Korea aan zeker tien mensen het leven gekost. Een onbekend aantal mensen raakte gewond. Daarnaast werden huizen en gewassen vernietigd. Noord-Korea werd vorige maand ook al getroffen door noodweer, dat leidde tot hevige overstromingen.
Muifa kwam maandagavond aan land in Noord-Korea. Ook het noordoosten van China gaat gebukt onder hevige regenval. Volgens de Chinese meteorologische dienst is er daar 13,5 centimeter regen gevallen.
In Noord-Korea is dinsdag meer dan 970 hectare landbouwgrond verwoest. Ook zijn meer dan honderd woningen met de grond gelijk gemaakt. De tropische storm kostte eerder in de Filipijnen al aan vier mensen het leven. Ook in Zuid-Korea kwamen vier mensen om. Hier worden bovendien twee mensen vermist.
Voordat Muifa aan land kwam, beschadigden door de storm veroorzaakte golven een dijk in China. De dijk, die een chemische fabriek in de stad Dalian moet beschermen, is volgens de Chinese autoriteiten versterkt met stenen en beton. Het gevaar voor de fabriek is afgewend, aldus Beijing.
bron: Accuweatherquote:Meteorologists in the AccuWeather.com Hurricane Center are still tracking the remains of Tropical Storm Emily, which passed very close to Bermuda Monday. A squall associated with Emily's remains caused a wind gusts as high as 51 mph at Bermuda's L. F. Wade International Airport. As of Tuesday morning, the storm was about 700 miles east-southeast of the island.
Since passing by Bermuda, thunderstorms have begun to cluster around the center and south of weak low pressure leftover from the storm. However, conditions are only marginally favorable for further tropical development in this area of the Atlantic due to lukewarm waters and strong westerly winds aloft.
AccuWeather Expert Senior Meteorologist Dan Kottlowski commented that Emily was looking fairly impressive overnight. "It may have actually been at depression or storm strength for a time, but now is becoming stretched out."
Emily's track has been governed by the midlatitude westerly winds that generally drive storms from west to east around the globe. However, some computer model forecasts are showing that Emily will take a turn to the south in the coming days and track around an area of high pressure that is currently centered several hundred miles southeast of Bermuda. If so, it could eventually end up over waters warm enough to regenerate again.
Some computer guidance that shows Emily turning southward indicate that over the next several days, Emily will curl around the persistent area of high pressure and wind up just north of the Virgin Islands. From there, a track toward the Bahamas again would be likely. Should Emily end up following this path, it should be over very warm waters with favorable wind shear and there would be a good chance of it to regenerate yet again.
It's worth mentioning that the computer model guidance is not in full agreement about Emily following a track that would give the storm a chance to develop into a tropical cyclone once again. Some show Emily stalling over the marginally warm waters southeast of Bermuda, while others show a continued track to the east that curves northward over time.
A track toward the east and northeast would take Emily to cold waters that would prevent further development, while a stall would keep Emily a thorn in the side of weather forecasters for several days.
Kottlowski also commented that, "It looks as though the lowest pressures and turning on the northern end of the cluster of thunderstorms. Most likely, the center of Emily tracks off to the northeast, but some of Emily's energy could get left behind would be a feature that we will have to track."
Kottlowski stressed that this sort of track would be unusual, and that other features had a better chance to develop than Emily. "I'm concerned about the area close to Florida later this week along a front that will become stationary in that area," he said. "We'll also have to watch the large area just west of Africa now, which probably will try to develop eventually once closer to the Lesser Antilles, though not before the end of the week."
