That's the TDWR out of San Juan airport!

Yes, I think we all agreed Nexrad is down...

BTW, through 24 hours, looks like core of Irene doesn't go through most rugged terrain of Hispaniola, but appears to catch a glancing blow of the Northeast side of the island.

Don't even get me started on this topic. The amount of priceless wx data (radar and surface obs) that has not been collected from the cores of landfalling hurricanes due to simple power failures it mind-boggling. It's such an easily remediable problem, and yet... ugh!

The WSR-88Ds are supposed to have a generator for situations just like this. ASOS equipment is a completely different matter and I will get upset quickly the more I talk about it!

Sorry, thought you were giving a local TV radar loop, since you had quoted LEK asking for a link to it. My bad!

Looks like the general trend in the last 12 hours of model runs is a somewhat stronger subtropical ridge, which makes sense based on current observations. Also, the GFS has trended deeper with the second trough that swings through the Great Lakes around 60-72 hours

Yea that's what I thought too. But doesn't land friction want to pull storms inland? I remember Phil saying something about that.

Meh, I think it's different for every storm. What about that other nugget-- don't storms want to follow the Gulf Stream? I dont think you can make generalizations with these storms like that.

For those looking, I couldn't see much on the BR from the San Juan TDWR, but I think I can see the center coming into view on the composite reflectivity (I just pulled it up so I only have a couple frames.)

Also, on a more OT note, anyone else forgoing sleep tonight to wait up for the Euro?
