NOAA P-3 mission has completed. Air Force is out there right now.







Pressure was extrapolated in latest vortex, not measured:

Location of tropical storm force wind field according to 10 second estimated surface winds by
SFMR instrument.

NW quadrant turn point:

About 5 HDOB icons west of first appearance of orange colored wind barbs, which are colored
based on flight level winds, was when 34 knots (39mph) started. [SFMR of 36 kts (41 mph)]

SE quadrant turn point:

SFMR of 41 kts (47 mph) which was noted as suspect, as well as one before of 44 kts (51 mph)
which was suspect. Before that 43 kts (49.5 mph).

NE quadrant turn point:

SFMR of 42 kts (48 mph)

SW quadrant turn point:

SFMR of 41 kts (47 mph) which was noted as suspect, but one before 43 kts (49.5 mph).

So you can see other than when they turned into the storm, they didn't sample the full tropical
storm force wind field. But you can at least how massive the wind field is based on just the wind
barbs alone and why there are tropical storm watches for parts of the coast.

And it's size allows it to push more water against the coast too, which is why there are storm surge watches.
