Hurricane Earl Forecast
Hurricane Earl Forecast:Graf was a very intense storm, the wind speed exceeds 140 miles (225 kilometers) per hour as it moved northward along the U.S. east coast.
However, as of Friday morning, the count decreased by 1 category hurricane with peak winds of about 85 miles (137 kilometers) per hour.
Although some damage was reported at the Outer Banks because of strong winds and flooding, the area has not experienced hurricane winds, “said Wallace Hogsett, meteorologist of the National Hurricane Center in Miami.
Forecasters say weak, but potentially still dangerous, the Count will pass over or very close to Cape Cod, Massachusetts (map), on Friday evening.

The second wall of the eye to put brakes on graph
Hurricane Earl weakened partly due to the phenomenon called the eye wall replacement cycle, said Keith Blackwell, a meteorologist at the University of Southern Coastal Weather in Alabama’s Research Center.
Very intense storms often experience this cycle, in which the second eye wall of a vertical wall of clouds around the eye is formed around the original. As a new eye wall is closed around the eye, it acts as a braking system, slowing the momentum of the hurricane and its winds caused a temporary decline.
The new eye wall would eventually replace the old one, and the hurricane could regain power, which is often stronger than it was before.
“Very powerful external walls are formed around the eye of Hurricane Earl,” said Blackwell. “By evening yesterday, the inner wall of the eye nearly collapsed. This led to a sustained weakening of [the storm].”
By the time the cycle was completed, the storm is faced with devastating upper-level winds known as wind shear, Blackwell said. Earl “may have reintensified after the destruction of the inner eyewall, if he did not feel a strong wind shear.”

In addition, the approaching low pressure system from Canada have helped to push the count a little further east, so that his eyes, which is surrounded by strong winds, storms, remained about 80 miles (129 km) from the coast of Cape Hatteras, Blackwell said.
The count is expected to decrease to a tropical storm with peak not more than 73 miles (117 kilometers) per hour on the road to a possible landfall Saturday in Maritime Canada

Updates:Hurricane Earl Forecast
Updates:Hurricane Earl Forecast:As fast as the growing and intensified hurricane graph is already beginning to disappear. Long Island should not let their vigilance, however, before the eastern part of the island can still be almost the full weight of what the graph left to give.
As of 8 am, the National Hurricane Center has downgraded Count Category 2 strength on the Saffir-Simpson scale of hurricane, the storm is expected by the Greater New York City as a strong Category 1 on Friday night.
As you can see in the Storm Journal of Tracker, the count took a jog east at the last second before the closest approach to the space at night in North Carolina Banks Thursday. This unexpected deviation, probably spared from the North Carolina coast from the strong effects of the graph, and, fortunately put an end to the hurricane westward shift of the previous few days. Greater New York also take advantage of this new shift in the east, since a significant portion of the graph will remain offshore winds when the storm visits our area on Friday evening.
Despite the easing trend, the chances of feeling tropical storm force effects in the Hamptons is not diminished by our forecasts Thursday: Montauk chance of tropical storm conditions are still 70%. Elsewhere in the region, coastal New Jersey and Connecticut face 33% chance, and in the subway in New York at 25% of the frame.
To give you an idea of why the chances of Eastern Long Island, the strike did not improve, let us return to a discussion Wednesday about the “eyewall replacement cycles. It is extremely intense hurricanes (eg, count on Thursday morning) will start to mature, they often shed a strong ring of wind in essence, to make room for new, more powerful eyewall in its place. This process also has expanded slightly weaker tropical storm force winds within the hurricane territory – sometimes up to 200 miles or more from the center.
This is exactly what happened with the Count Thursday night. In the case of the count, however, the new eyewall was due to take over, particularly in colder water temperatures encountered a hurricane to the north of the Gulf Stream. As a result of these effects, the passage of the count in the Hamptons, probably now resemble a strong Noreaster winter – minus the snow, of course. Flooding, coastal erosion and disruptions in the supply of electricity is still likely.
These brave readers have left a storm in eastern Suffolk County can monitor graph using the reports from the National Oceanic and Atmospheric Administration buoy close to shore. As the Count and the fall of air pressure, wind speed starts to grow. In addition, the wave height over 10 feet. Expect significant waves and rip currents will continue throughout the rest of the holiday weekend.
Even more boldly, as you view a graph of the cockpit NASA DC-8 aircraft? Science Journal columnist, Lee Holtz, interviews with the pilots on Thursday. NASA pilots also shared the video of their flight through the eyes of the graph through YouTube. (Their colleagues from the International Space Station also shared the graph frames, by the way. Go to 10:17 in this video for the closest approach.)
I’ll stick to watching the graph with my laptop, thanks.
