Hurricane (or soon to be) Katia

August 31st, 2011 · No Comments

Sometime this afternoon, after further aircraft reconnaissance missions through the circulation of Katia, it will likely be determined that hurricane force winds have been established.  This will make for the 2nd hurricane of the season.

Katia will likely intensify into a major Category 3 hurricane by this weekend, but is expected to remain mainly over water with very minimal impacts through the weekend.  Atmospheric steering currents will likely bear a re-curving effect on this storm directing it northward into the Atlantic.  (*Note this steering current is often due to a Atlantic Subtropical high pressure system, or a Bermuda high)  At this point concern for a landfall on the US coastline appears to be low. 

On the other hand, computer models indicate tropical wave over the Gulf of Mexico may have a more immediate effect on the United States.  Pictured below is the GFS forecast model valid Sunday afternoon.  Notice the tropical development in the Gulf of Mexico.

Irene gone, Hello Katia?

Then Tropical Storm Irene as the eye passes over New York City

As of 11am Monday morning, Irene is no longer considered a tropical system. Although the storm produced maximum wind gusts to 115mph in parts of North Carolinas shore, the system will long be remembered for the historic flooding.

North Carolina Wind Gusts

Pennsylvania Wind Gusts

New York Wind Gusts

New England Wind Gusts

An example of the extreme flooding occuring in New England, in particular Vermont, as a result of heavy rains from Irene.

All is quiet now over the Atlantic, right? Not even close.
While parts of New England was being flooded and battered by Irene, Tropical Storm Jose formed. You might have asked, ‘why haven’t I heard about Jose?’.  The answer is simple. It was a short lived storm which developed and quickly died out in a matter of 2 days.

Monday morning satellite picture. I = Irene, J = Jose. Both are no longer tropical systems.

As if that wasn’t enough, another tropical system is on the verge of being named. As it stands right now Tropical Depression 12 only bosts winds of 35 mph but is expected to strengthen to Hurricane status by weeks end.  It would earn the name Katia, replacing Katrina in the hurricane name rotation (Katrina was retired after 2005). As you can see from the map below, this storm has over 2 weeks before it would even be within range of striking the US.

Soon to be Katia's projected path, per the NHC.

 You get the scope of how far away Tropical Depression 12 is from the United States when you look at the satellite view. Only a stones throw from Africa.

Predictions before the hurricane season said this would be an active year….so far that has been the case.

“The category of the storm does not tell the whole story.”

August 28th, 2011 · No Comments

“The category of the storm does not tell the whole story,” FEMA Director, Craig Fugate, reminds folks. Major concerns surrounding Irene are not in intensity nor organization — they are flooding, storm surges, and heavy downpours.

As Irene heads right for NYC, street level waters rise, and areas of the heavily populated city become unrecognizable under a sea of flood water. Still categorized as a Category 1 Hurricane, Irene is carving a path of destruction up the coast, and authorities are having some of their worst fears confirmed.

The storm’s landfall is expected midday in NYC Sunday. Reports from yesterday recorded anywhere from 12-24” of rain in areas of North Carolina, and an estimated 10” in Delaware. Irene is still pulling significant moisture from the ocean, so similar rain levels can be expected in the New Englad states for the second half of the weekend.

Hurricane Irene: Update Saturday — 5AM

August 27th, 2011 · No Comments

It has been 1077 days since a hurricane has made landfall in the United States. The last cyclone to hit the U.S. was hurricane Ike on September 13, 2008. After nearly three years, we’ll reset that number back to zero today.

As of 5am Saturday, Irene is directly over the Outer Banks and NC coast with 90 mph sustained winds and gusts of nearly 110 mph. The storm has been downgraded to a Category 1 due to a slight decrease in intensity, but that’s not to say the threat of severe weather (and consequences) has diminished.

Airports are shutting down, areas of NYC are being mandatorily evacuated, public transporttaion is coming to a hault, professional sporting events are being rescheduled,  and the entire East Coast is preparing for one of the largest impacts from a hurricane in decades.

President Barak Obama has called Irene “extremely dangerous and costly” storm.

Hurricane Irene Update — 1 PM Friday

August 26th, 2011 · No Comments

Within the next 24 hours Irene’s extreme impact will be felt across North Carolina.  She is now expected to make landfall as a strong category 2 hurricane.  A slight decrease in the intensity is due to upper level shear it is battling just off the eastern seaboard.  This shear and the slightly weaker projection is a sliver of good news in an otherwise dire situation that still exists.  Severe coastal flooding and erosion, inland flooding and damaging winds are still all major hazards through the weekend all along the east coast.

The second landfall is still expected through the day Sunday on the Island of Long Island.  This could be the strongest hurricane to hit Long Island since Hurricane Gloria in 1985.

Hurricane Irene Update-9 AM Thursday

August 25th, 2011 · No Comments

The latest analysis indicates Hurricane Irene could have devastating impacts from the Carolina’s through New England this weekend.  Model consensus show initial landfall around the Outer Banks (pictured below) late Saturday evening.

GFDL-Landfall of Irene Sat. PM (North Carolina)

The GFDL model depicted above actually is showing the landfall point west of other model consensus.  I expect, and agree with the NHC forecast path which is expected to be west of this point over the eastern tip of the Outer Banks. 
Irene then is expected to emerge into the Chesapeake Bay area and head northward with a second landfall possible over Long Island, New York.
 

NAM Sea Level Pressure and Precipitation forecast for Sunday morning 8 AM

This could be one of the most powerful hurricanes in decades to impact Long Island, New York City and New England and could have devastating and deadly consequences brought on by coastal flooding, inland flooding, and intense winds.  Stay tuned for updates!

Hurricane Irene: Cat. 3, Major Hurricane

August 24th, 2011 · No Comments

A status change for Irene makes her a major player in this week’s weather for a large portion of the United States.
Hurricane Irene has strengthened to a major Category 3 storm as it heads toward the East Coast.
Hurricane Irene is gaining strength on a course that may take it near North Carolina this weekend and into southern New England early next week. Not only that, but with a max sustained wind of 120 mph and 150 mph gusts, Irene packs a big punch, and areas under the gun next week include Washington DC, New York City, and Boston.

Evacuations have begun on a tiny barrier island off North Carolina early Wednesday in a test of whether people in the
crosshairs of the first serious hurricane along the East Coast in years will heed orders to get out of the way.

Irene is centered over the Bahamas Wednesday and is moving west-northwest near 12 mph.

Not convinced? Look at this:
“Irene is an extremely dangerous storm,” says Jeff Masters, co-founder of Weather Underground Inc. in Ann Arbor. “It has the highest potential of any storm in the last 50 years to make it all the way to New England as a Category 3.”
We’ll continue to track Irene and keep you posted.

Irene Update — 1PM Tuesday

August 23rd, 2011 · No Comments

Hurricane Irene is expected to become a major category 3 hurricane by this evening as it roars toward the Bahamas.  The eastward shift in the hurricane path and computer models continue to be a trend and it is something I’ll continue to monitor this week. 

(Enhanced IR Satellite with forecast path and various model projections)

All major cities on the East Coast are on high alert for impacts from this hurricane which include high surf, heavy rains, storm surge with inland flooding and strong winds.

First Atlantic Hurricane

August 22nd, 2011 · No Comments

Hello Irene!  The first hurricane of the Atlantic Basin has arrived.  With winds now at 75 mph it is expected to graze the Dominican Republic, Haiti and Cuba before driving into the Bahamas en route to the Atlantic coast of Florida.  At this point there is a HIGH probability of a landfall at hurricane strength on the US mainland.  Here is the most recent satellite imagery:

Here is the latest hurricane track and position of Irene by 5 PM on Friday as a category 2 hurricane:

Me, Myself, and Irene

August 21st, 2011 · No Comments

As of 1pm Sunday, Tropical Storm Irene is dumping heavy rain on the northern Leeward Islands and the system is expected to strengthen as it heads toward Puerto Rico. The National Hurricane Center says Irene could become a hurricane Monday, especially if its track takes it primarily over the water, where it is more likely to gain speed and energy. So far, the 9th named storm of the 2011 hurricane season has maximum sustained winds of 50 mph.  Sustained winds must reach 74 mph for the storm to become a hurricane.

 A projection of Irene’s track have it moving directly through Puerto Rico Sunday, into Cuba Wenesday, and into the southern coast of Florida by Friday.
