Irene Recon Reports

[Matt-hurricanewatcher]

I wonder where they got that 991 milibars from? Also this system looks weak.

This is the same as the last one, at 5:26Z..but the pressure is corrected. Its 996, not 998.

Doing another late flight today for the 00Z runs

[wxman57]

The fact that the plane did not find that broad 80nm wide ring of convection overnight is a good sign that Irene may be developing today. Winds should now be able to spiral into a tighter center as the day progresses. But Irene is clearly not going to affect the east U.S. coast.

[Derek Ortt]

while I agree that this is likely to stay offshore, the GFS has again butchered the 500mb forecast, even after the dropsondes. The 12 hour forecast from last evening already had the ridge offshore, when it is clear that this is not the case based upon the obs. Still some chance to make a close pass to the Cape

That is not the scheduled flight, maybe a training mission. Maximum winds for that flight were 55 knots. The scheduled flight just sent this in:

NW quad, the second plane. They are now entering the center.

By the way, the NHC 11 AM position was too far north by 0.3 degrees, but motion in the past 2 hours has been almost due north.
