Routing Because Of Irene

Sat Aug 27, 2011 2:22 am

Looking at some of the flights from the northeast to south Florida, there are some interesting routings to give Irene an understandably wide berth as she starts to make landfall in North Carolina and up the coast. In some cases it looks like flights are going almost 300 miles out of their way:

Wow, those are definitely some interesting tracks!! Well, I guess there really wasn't an option as the storm pushed a lot of flights to take over-land routes that normally wouldn't. B6 normally uses over-water routes, in fact I've been on JFK-Florida flights where I couldn't even see land. So that pushed a lot of extra volume into (most likely) already crowded inland routes.

Nice catch catiii

Earlier in the week when the storm was over the northern Bahamas - everything headed to MIA, FLL, PBI was flying down to Tampa and then east across the Glades to those airports. Departures also taking that route.

What are the tops like in a hurricane? I always thought airliners could easily overfly them.

It's the associated storms that are the problem. Currently the tops of the storms, which spread out anywhere up to 200-300 miles from the center of Irene, are FL350-550.

So... there is no overflying those storms, and there are also no breaks in the cover. It's a 200 miles radius of weather FL350 and above.

While sometimes aircraft could overfly such a storm - most airlines will not want to do so.

Should there be any problem, they want to be able to divert. And they certainly would not want to have a pressurization problem and have to descend into the middle of such a storm.

It is just safer to go around - and it is a relatively minor cost on the scale of an entire year of airline operations.
