No... a Cat 5 is closer to 920-925 mb.

938 mb is closer to 140-145 mph. 950 was a little high for a Cat 4 anyway.

I'm stunned... Ok... stunned... that's one heck of a recovery sliding along cuba!

The pressure drop is really the big story here. 12 mb in just 5 or 6 hours. Wow. :eek:

Unbelievable... WOW.

clfenwi · #30 Postby **clfenwi** » Fri Jul 08, 2005 7:35 am

For perspective, 938 millibars is three millibars lower than Charley's pressure at landfall.

How soon before they get readings for the NE quadrant?

Stratusxpeye · #32 Postby **Stratusxpeye** » Fri Jul 08, 2005 7:41 am

Wow this is amazing. 938 mb and you know it will get lower. Could we see CAT 5 At 11am adv?

Not a Cat 5. Pressure is too high.

145 mph is a good bet though.

Lets all wait for the analysis of the NE quadrant.

Matt-hurricanewatcher · #37 Postby **Matt-hurricanewatcher** » Fri Jul 08, 2005 7:48 am

The winds most likely will be stronger over the northeast quad.

Stratusxpeye · #38 Postby **Stratusxpeye** » Fri Jul 08, 2005 7:49 am

Thats my assumption. 140 in SE Quad. Most Likely 145 150 OR SO IN NE QUAD. Thats amazing.

Thunder44 · #39 Postby **Thunder44** » Fri Jul 08, 2005 7:54 am

Unless the pressure falls more, I wouldn't expect the winds in NE quad to be much higher than the SE quad. Generally the north and east sides of storms these are always where the strongest winds are.

Matt-hurricanewatcher · #40 Postby **Matt-hurricanewatcher** » Fri Jul 08, 2005 7:56 am

The northeast is much stronger then the southeast quad. By about 20 mph on norm.
