Costa leste dos EUA se prepara para dilúvio com aproximação do Joaquin
Na costa leste dos Estados Unidos são esperadas, este sábado, chuvas torrenciais e ventos muitos fortes com a passagem da tempestade tropical Joaquin.
03 Out, 2015
Foi declarado o estado de emergência em muitos estados norte-americanos devido à passagem da tempestade tropical Joaquin.
Da Georgia até Nova Iorque, as autoridades estão de alerta para qualquer emergência que chegue devido ao mau tempo.
Entretanto já há registo de várias inundações na região da Carolina do Norte, com relatos de cortes de energia e queda de várias árvores.
As autoridades meteorológicas avisam que tempestade tropical “Joaquin” vai provocar muita chuva e ventos que podem atingir 200 quilómetros por hora.

The East Coast’s Heavy Rains Are Not From Hurricane JoaquinRight now, the East Coast is getting drenched by some nasty Atlantic moisture. But there are worse things than rain. Take wind, for instance, or heavy seas. Or maybe take a hurricane, like the one that’s been squatting over the Bahamas.
At a regional scale yes, the storm and the hurricane are related (all weather is related, that’s why it’s so hard to predict). But Joaquin isn’t the source of the southern US’ current water woes. Rather,some wonky upper-atmospheric conditions are forcing wet Atlantic air onto the continent—conditions that are also directing the course of that ominous cloudy spiral to the south.
No matter how much it looks like it (especially in the gif above), the guilty-looking gyre isn’t to blame for the rain. “The rain over the southeast states has nothing to do with Joaquin,” says Dennis Feltgen of the National Hurricane Center in Miami. Joaquin is about 300 miles across. But at its current location—just off the shore of the tiny island of San Salvador—Joaquin is about 365 miles southeast of Miami.
The pattern you see in the gif above is actually high elevation moisture coming off the hurricane and getting swept into the jet stream’s upper atmospheric flow. “The question is whether moisture out of the surface is coming out of the hurricane and into the east coast storms,” says Christopher Davis, a scientist at the National Center for Atmospheric Research in Colorado.
Which also has to do with the jet stream. Like Joaquin over the Bahamas, the east coast’s weather system has been camping out. This is because the jet stream—the upper atmospheric westerly that affects surface weather—has a big kink. Centered near the Florida Panhandle, that kink has a low pressure system which pushes moisture to the east. After the kink, the jet stream’s flow turns north, tracing the eastern seaboard. This weird pattern is messing with temperature and wind patterns, and the result is the stagnant storm.
The jet stream’s kink is also a big reason why meteorologists currently predict that Joaquin will shoo away to the north.
This combination of a far-south jet stream and hurricane is unusual, but not unheard of. Sandy earned its “superstorm” designation because of a similar situation. “The difference was that Sandy and the weather system merged and became one very big storm,” says Davis. “And apparently that’s not happening in this case.”
Right now NOAA is predicting that the storm will move north, but stay offshore. But even if it veers a little bit towards land it could pile waves and water atop an already saturated seaboard. New Jersey Governor Chris Christie has declared a preemptive state of emergency just in case of such an eventuality.
Because as bad as things get, they can always get worse. Even in Jersey.

Heavy rain causes flooding, power outages in Charlotte region
Driving distance from Charlotte to Lenoir (Dacentec): 74 Miles / 120 Km
Heaviest rain gradually shifting westward, threatening foothills and mountains next.
A pipeline of tropical moisture fed in part by Hurricane Joaquin brought hours of heavy rainfall to the Charlotte region overnight, downing trees, causing scattered flooding and knocking out power to thousands of customers.
Emergency management officials rescued more than a dozen people from flooding in Myrtle Beach, and authorities in Charleston closed off parts of the city to tourists because of heavy rain.
The rain, falling heavily at times, was continuing across much of the area at daybreak Saturday, although meteorologists said the pipeline – which stretches from the Atlantic Ocean across Charleston and central South Carolina into western North Carolina – was nudging slowly westward.
By 9 a.m., the rain had tapered off to showers from Charlotte eastward.
"Eventually, we expect the area of heavy rain to pivot southward into South Carolina," said Doug Outlaw, of the National Weather Service office in Greer, S.C. "That area will be just south of Charlotte."
The Weather Service continues to warn that dangerous flooding is expected later Saturday in a corridor from the South Carolina coast, eastward across Florence, Columbia, Greenville-Spartanburg and Athens, Ga.
In the Charlotte area, intermittent rain is expected to continue through Sunday. Another growing problem Saturday will be winds. The National Weather Service says steady winds of 15 to 20 mph, gusting at times to 35 or 40 mph, are expected to develop during the day and continue into Sunday.
Harry Gerapetritis, of the National Weather Service office in Greer, S.C., said there have been scattered reports of downed trees. "This should worsen," Gerapetritis said.
Authorities said there were several reports of trees falling on houses in Mecklenburg County overnight.
While rain tapers off for Charlotte and points east, several hours of heavy precipitation is expected throughout the day in the foothills and mountains, where emergency management officials fear landslides and life-threatening flash flooding could develop.
Advisories for urban flooding and small stream flooding are in effect until late Saturday morning for Mecklenburg, Union, Anson, Stanly, Montgomery, Richmond, Cabarrus, Rowan and Iredell counties.
Most of Mecklenburg County has received 3 inches of rain in the past 24 hours. Totals were heavier to the east, which was caught in the tropical pipeline for several additional hours. South Carolina emergency management authorities said about 6 inches has fallen in Chesterfield County, and there are widespread reports of 4 to 5 inches of rain in Stanly, Anson and Montgomery counties.
At 9 a.m., Duke Energy was reporting more than 7,000 power outages in Mecklenburg County. Another 1,500 outages were noted in Rowan County. Other area counties had much smaller power outage numbers.
Charlotte-Mecklenburg police report minor flooding and downed trees blocking roads in several locations, although most main roads were reported open. The biggest problem was a downed tree reported at South Wendover and Sharon roads in southeast Charlotte.
The heavy rain is being caused by a combination of factors – an upper level low pressure system parked over the Florida Panhandle, high pressure over New England bringing a flow of moist air off the Atlantic, and a surge of tropical moisture from Joaquin, which is hundreds of miles offshore.
HEAVY RAIN, FLOODING
The National Weather Service said Goose Creek near Fairview in northern Union County is flooding, and roads in the area are under water. Cabarrus County authorities reported flood-prone Stallings Road near Harrisburg also was flooded and closed.
Statesville Road west of the town of Cleveland in Rowan County also was closed by flooding, authorities there said.
Motorists told The Observer about numerous flooded roads at daybreak Saturday in southeast and south Charlotte. Most of that flooding was subsiding by mid-morning.
Authorities said the heavy rain and gusty winds will continue to cause trees to come down. Early Saturday morning, downed trees were reported on Tippah Drive and Country Club Drive in the Plaza Midwood area, and at Sharon and Wendover roads in southeast Charlotte.
Two people escaped injury in northwest Mecklenburg County overnight, when a tree fell on a house on Long Grass Court near Auten Road. A tree also fell on a house on Rodey Avenue in north Charlotte, briefly trapping two people. They were not hurt, authorities said.
Chester County authorities reported several downed trees north of Fort Lawn.
Police responded to several multi-vehicle wrecks late Friday and early Saturday, including at least three on Interstate 485 in south Charlotte. A truck jackknifed about 7 a.m. Saturday on Interstate 85 in Gaston County, shutting down the northbound lanes.
There were widespread reports of 6 to 10 inches of rain falling in Horry County. Authorities there said many roads were closed by flooding. About a dozen people were rescued from flooded homes in Myrtle Beach, and about 50 houses were evacuated in the fishing village of Calabash, along the North Carolina-South Carolina border.
The Charleston police announced at 6 a.m. that vehicle traffic was not being permitted in the lower part of the city. Numerous roads were flooded in the city, where between 6 and 8 inches of rain has fallen since Friday afternoon.

200-year rains batter the Carolinas
Obama declares state of emergency in South Carolina over floods.
Some 22 million Americans are under a flash flood watch as the rains continue to fall, with meteorologists saying up to 15 inches could be recorded by the time the rains abate, perhaps as late as Sunday night. That would make it an event that hasn’t been seen since before the Civil War, and perhaps not even since the explorer Hernando de Soto crossed the South.
President Barack Obama on Saturday declared a state of emergency in South Carolina after severe storms caused widespread flooding, the White House said in a statement.
Obama ordered federal aid to supplement state and local response efforts and authorized federal agencies to coordinate disaster relief efforts, the statement said.
Rain pummeling parts of the east coast showed little sign of slackening Saturday, with record-setting precipitation prolonging the soppy misery that has been eased only by news that the powerful hurricane Joaquin will not hit the US.
The Carolinas will probably get the worst of it, including possible landslides in the mountains, experts said. South Carolina could get more rain in three days than it normally gets during the entire fall.
“It’s going to be a slow-motion disaster,” said meteorologist Ryan Maue of Weather Bell Analytics.
Bottom line: Columbia, S.C., and Charlotte, N.C., are getting soaked. Weather-watchers reported as much as 12 inches of rain falling on Wilmington, N.C., overnight into Saturday. Local authorities were reporting that multiple water rescues are taking place. North Carolina officials were reporting 17,000 power outages across the state, and police said one woman has died due to the weather after a tree fell on her car as she was driving down I-95.
The colonial-era city of Charleston appeared to be taking the brunt of the heavy rains on Saturday, as residents could be seen paddle-boarding through the city’s historically low areas.

Battering Coastal Storm Slams Tri-State With Flooding, Rain
Strong winds, heavy rain, flooding hit New Jersey region
A drenching rain continued to soak most of New Jersey on Saturday, spurring minor flooding in some areas and washing a Jersey shore home into the water.
The storm had also caused scattered power outages throughout the state, with about 3,600 utility customers having no service as of early Saturday afternoon. The rains had also slowed down traffic on the state's major roadways, including the Garden State Parkway and the New Jersey Turnpike, but no major travel issues were being reported.
The wet weather is expected to continue through the end of the weekend, and a coastal flood warning for the state was due to remain in effect until Sunday evening. About two inches of rain had fallen in most areas since Wednesday, and forecasters said another 1 to 2 inches was possible by Sunday night.
The weather system comes on the heels of what was thought could be a devastating hit by Hurricane Joaquin, which was projected to head directly toward the region in the initial models earlier in the week. Joaquin now appears be heading back out to sea as it moves northward.
Coastal communities were bearing the brunt of the storm, as the heavy rains and high tides battered the region.
No fatalities were being blamed on the storms, but they did dislodge an entire house from its pilings in a low-lying area of Middle Township in southern Jersey. The remnants of the home could be seen in Grassy Sound after daybreak Saturday, and residents there were bracing for the possibility of moderate flooding Saturday afternoon.
No one was in the residence when it dislodged, and authorities said the matter remains under investigation.
Joe Clifford, who lives in the neighborhood, told The Associated Press that the house broke loose and went by his home, then hit and a few decks out in the water and struck his 18-foot boat - which capsized - before it went out to the bay.
"(The house) is just sitting down in the bay now, it's in pieces," Clifford said.
While Superstorm Sandy destroyed decks and caused other damage in the area when it hit three years ago, Clifford said he had "never seen anything" like the storm that hit Friday night.
"The winds were incredible, and everyone didn't get their boats out in time," he said. "There was lots of destruction from winds. We knew there was going to be a storm, but we didn't know it would be this severe."
