Wow. Can really see the surge now. Wind has picked up at my house in the last 15 minutes.

I hope the cam survives. It still has not seen the high winds.

Airport is reporting sustained winds of 22 kts (24-25 mph) with peak gusts 37 kts (42 mph). That one band of squalls might be able to produce sustained winds of 40-45 mph.

Nate is fascinating to me. How is such an inefficiency of mixing winds to the surface possible? My initial guess is dry air, but as was pointed out during Irma’s landfall in Florida, the subsistent quality of dry air would likely result in significantly higher gusts despite meager sustained winds. Radar would would seem to suggest the most intense part of the storm is on land now, but peak winds of 50mph, gusts to 60mph are baffling to me, considering that recon reported fl winds up to 89kt I believe (according to the latest advisory).

Do any of the pro Mets have any insight to this?

Clearly Nate felt that he had been standing for a bit too long, and was trying to offer him a seat. :lol:
