Hurricane Sandy Morning Update

Submitted by Mike Francis, Chief Meteorologist

Friday, October 26th, 2012, 11:33am

The latest from the hurricane center has Sandy as a category 1 hurricane with winds at 80mph. From the image below you can see that Sandy has taken on some big time shear today and has lost all the convection around the center of circulation.... Thus pressure has been rising in the center of Sandy since all the convection has been pulling off to the north. T

he hurricane center talks about shear decreasing over the next 24-36 hours, but I think it will actually increase a bit..... then decrease significantly as it starts to drift back out towards the NE.... I think indirectly at this point in time Sandy DOES feel the effects of the northern and southern jet in the form of coupling and evacuating all the mass.... I think by Sunday afternoon Sandy will decrease in pressure rapidly down into the 930's then begin its transformation to extra tropical and turn back towards the west.

We will continue to cool down Sunday and next week. Clouds will gradually clear out Sunday. Highs will be in the low 60s. By Monday, highs will be in the 50s.

Massive "Superstorm" to Slam The new England States, Effects for N Georgia

For the last several blogs I have been talking about where Sandy is going to go and why she is going to go there. I have also focused on the things that are going to make Sandy become a BIG DEAL for the NE... This blog I am going to go in depth into the dynamics of WHY Sandy is going to become a freak hybrid superstorm... For that I am going to focus on one specific time period and delve into the dynamics of what makes this storm potentiallly so spectacular!

If you are reading this for the first time and want to see the resaoning behind why I think Sandy will be going in the direction I have forecasted check out the blog from Tuesday night when I first started talking about her:

They Are Calling It Frankenstorm... Effects on N Georgia

Frankenstorm

Yes, every storm gets a name when it comes to the worst of the worst.. "The Perfect Storm", or "Snowmaggedon", or "Snowpocalypse"..... The reason for the term "Frakenstorm" is simple... It is a freak hybrid that if it comes together, is the perfect blend of a mid lattitude cyclone and a major hurricane...... A lot of people have asked me how a storm becomes a "superstorm" and the answer is complex, but I will try to explain.

10am Update for Hurricane Sandy and Impacts on N Georgia

10am Update for Hurricane Sandy and Impacts on N Georgia

As you can see from the current track above, Sandy is crossing over Cuba as we speak. As she came ashore earlier this morning she was a beast, winds were at 110mph sustained with even higher gusts... Flight level winds for the hurricane hunter were as strong as 130mph at times. Simply put, Sandy is a very powerful storm and will likely re-gain strength when she gets back to open waters later this morning.

The latest track from the hurricane center is all based on the 6z (2am) computer model runs, however the new ensemble runs are out and again have shifted its track back towards the west.... Some even have this beast of a storm hitting DC as early as Monday night. It is too early to tell exactly what will happen with Sandy but everyone along the east coast from Norfolk to the northern tip of Maine needs to be aware of this storm.

Dry, and sunny skies continue to dominate our skies today. Highs will be in the upper 70s. Another nice day on tap. The dry weather continues Friday, but a cold front will move in Saturday, bringing a slight chance for showers. Behind the front, temperatures will really cool down. Highs will be in the low to mid 60s next week.
Hurricane Sandy will be watched closely as the storm heads toward the east coast of Florida Saturday. The storms is forecast to pull away from the southeast coast Sunday, and then bend back toward the Northeast coast and make a possible landfall in the New England area next week.

What Does it Mean When a Storm Bombs?

Bomb Cyclogenesis

Ok, what is a bomb in the world of weather... Simply put, in non meteorological terms it is when all hell breaks loose inside a storm. For the technical definition: Bomb cyclogenesis is when a storm's pressure falls 24 milibars in 24 hours!! Like I said, all hell breaks loose!! Typically this happens with coastal lows, or Noreasters, but sometimes it happens with tropical systems! Here is a list of some of the most famous bombs:

From my friends at Wikipedia:

In 1983, Super Typhoon Forrest underwent one the most explosive deepening events ever recorded with the pressure dropping from 975 to 885 millibars as it went from a tropical storm to a category 5 super typhoon in 24 hours.
