October 25, 2012
— Open Blogger A late good evening, Morons and Moronettes, from the AoSHQ Weather Desk. It seems like we just did this last year with Hurricane Irene, and Sandy is a very rare bird indeed. For the moment, however, let's concentrate on what we've got in the short term, and we'll move to the longer-term implications shortly.
Forecast map and discussion below the fold...

As of the 11 PM EDT advisory, Hurricane Sandy is a strong Category 1 hurricane, with winds of 90 mph sustained and gusts to 115 mph. Motion is roughly NNW at 12 mph. Minimum pressure is 968 millibars, which is fairly impressive.
Okay, so the first thing that jumps out in the map above is the big swing back to the northwest as it approaches the Tri-State area. That's pretty rare for Atlantic hurricanes; usually, they turn east and keep going. So let's talk about why that's happening.
Tropical systems take the path of least resistance. They tend to thrive under high pressure and get torn apart by areas of low pressure. It's currently getting torn up by its interactions with a low pressure area over Cuba. Sandy is forecast to interact with a series of low pressure features that will drag it north, then north-northeast, then finally back to the northwest (as of this model run).
National Hurricane Center (NHC) guidance has Sandy making an East Coast impact somewhere around a Category 1 hurricane or a strong tropical storm, but here's the rub- this is using the hurricane modeling, and that may not take into account that Sandy will lose its tropical characteristics as it transitions into what we call a hybrid system- a mix of a tropical cyclone and an extratropical system. There are characteristics of both, but they're more unpredictable. Therefore, allow for pretty broad fluctuations in course.
For the moment, expect high surf along the East Coast, and if you're anywhere from Philadelphia through Boston, you'll probably want to prepare for hurricane conditions to make their presence felt late in the weekend. As things clear up in terms of forecast solutions, we'll have more information. This should be a pretty messy storm to forecast, and bear in mind that this is a REALLY BROAD storm... several hundred miles in diameter, and asymmetric. That means the weather will be crappy for hundreds of miles in either direction from the center of circulation.
So, to close, begin your preparations NOW anywhere from Wilmington, DE/ Philadelphia, PA all the way up through the Maine coast... consider last year your dress rehearsal for this.
If you need to get a hold of me with questions, find me on Twitter at @tmi3rd. I'm going to spend the rest of the evening practicing my coughing. tmi4th occasionally brings home colds from daycare, and this one's a whopper.

If you have gutters putting long extensions on the downspouts will be the quickest fix. Then it is landscaping or a tile system below the floor.

I certainly hope that President Romney and a Republican congress can stop this feeding food to our gas tanks. If anyone thinks this doesn't affect you, your grocery bill is a direct result. It's not just gas (if you don't drive), or milk (if you're lactose intolerant), or beef, pork and chicken (if you're vegan). It's everything. ALL of this stupid Gore-shit needs to end, or our country will.

49All of the models now say that Sandy will make landfall in the Northeast. They just disagree on where.

I work for FEMA and live on the west coast. We were told to get ready to travel east very soon. Dammit! This will be the second Thanksgiving in a row that I will miss. Last year it was Irene and i got stuck in G** D***ed Maryland!
I hate the northeast, particularly the winters.

No-Gaps consistant with itself and ECMWF with landfall southern Delmarva and march nw to Boalsburg Pa, home of the Boalsburg cow.. and me
So spread before ECMWF is Canadian in Maine, with GFS and UKMET at NYC.Amazing seeing No gaps with ECMWF so far. Poor scoring model
ECMWF takes storm as far west as 78.7... its done that for 8 straight runs now . Back down to 950 mb by 30 hrs as ne drift starts
If hurricane pulls GFDL then will be at parents with Garrett.Since he was 5 he wanted to ride out a hurricane with grandpa

Storms are driven by convection. Convection is driven by temperature differential. There are two ways to get it. You either warm up the water or you cool down upper air to get a big difference in temperature that causes the air to rise. At this time of year the gulf stream is still rather warm. Currently it is about 80F. It takes a long time for it to cool down compared to the atmosphere. The air aloft has already started cooling down. So there is a huge temperature difference. This storm is going to take advantage of the relative difference in temperature between a relatively warm ocean and a relatively cold upper atmosphere.

Hurricanes have been around since the earth was formed. It's called "Hurricane Season" for a reason, hurricanes occur during it. Hurricanes were happening even before "globull warming" was even an idea in the socialists global redistribution schemes.

Seriously, stay safe. I've seen it rain sideways at 120MPH at East Intercourse Island in 1976. Not too much fun.

Looks like it is not going to be a fun next several deays here in the Philly area. And most of our family lives in NJ within 5 miles of the Atlantic. Time to get a generator (if there are any left) and be prepared for some time without power. If this thing goes up the Delaware Bay, the damage will be catastrophic.

Once in a while one of these storms travels up Chesapeake Bay and clobbers Baltimore and points west. Sorry to disappoint the kids for Halloween but I think I'll stop on the way home tonight and buy up all the bread and toilet paper at the local grocery store.

Preparation... Water, water, water. Food that can be eaten without cooking. Think fruit... banana, oranges, grapefruit, apples, etc. Prepare to lose the use of your refrigerator and look at the food that is in it now. Anything expensive you could eat in the next two days? From experience I can tell you that within 24 hours, stuff in the freezer is useless.
Outside: Lawn chairs, tables, anything that can get blown around will get blown around. Stack chairs together then put them on their sides then tie them to something secure, you really don't want to go running around outside to retrieve a table in high winds and torrential rain. Blow your gutters out if they're full of leaves.
Looks like I know what I'm doing today.

This can't be any worse for Connecticut than last year's surprise snow storm that left many without power for 2 plus weeks. I had power at home, but no one around us did and we were out at work for over a week. Every morning I would go in and fire up the generator and hook up the computer so I could do payroll and stuff. It was kinda fun except that I lost some really nice large bushes in my backyard that provided a nice privacy fence, with the leaves still on the tress the snow just weighed them down so much. I went out as soon as it was over and shook off as much snow as I could, but the damage was already done.
Also, another good reason to not buy Halloween candy.

The airline won't cancel the flight until a day or so before schedule. In my case, a flight was canceled due to flooding and alligators and snakes on runway due from tropical storm.
If you cancel in advance you will be credited for flight but have to pay an additional fee. I'd wait or leave Sunday if you haven't paid for ticket in advance. Sandy can and will change cone of impact. Or not.

Let me be clear. This a storm likes of which we've never seen. The damage will be horrendous. For reasons of public safety, I've decided to cancel the elctions until we've fully recovered from this distaster.
