Seems like we might have a hurricane tonight.

Uh-oh!

Don't pay attention to line D. Look at flight level winds then take the reduction. Doesn't get you 70 mph.

#88 Postby **seahawkjd** » Sat Aug 28, 2004 2:28 pm

thought he was getting his act together, definetely more then 22 kts lol

maybe its not an ittybittybay then...

OtherHD · #91 Postby **OtherHD** » Sat Aug 28, 2004 2:30 pm

A 90% reduction gives 60 mph.

lilbump3000 · #92 Postby **lilbump3000** » Sat Aug 28, 2004 2:30 pm

It might be 70 mph with dvorak estimates to back it up at T3.5/3.5. But as for now the NRL site has it at 45kts.

#93 Postby **seahawkjd** » Sat Aug 28, 2004 2:30 pm

so 65 mph with the reduction?

Matthew5 · #94 Postby **Matthew5** » Sat Aug 28, 2004 2:31 pm

Max Flight level winds only 59 knots? That works out to around 45 knots at the surface.

Derek Ortt · #95 Postby **Derek Ortt** » Sat Aug 28, 2004 2:31 pm

Dont want to alarm anyone, but Gaston has been exploding at a rate of 2.5 T numbers per day. I'll let you all to extrapolate that to get what the landfall intensity would be if this trend continues

krisj · #96 Postby **krisj** » Sat Aug 28, 2004 2:34 pm

Well, fill me in, cause I live in Charleston! Not much talk going on about Gaston here. When should he make landfall?

Guest · #97 Postby **Guest** » Sat Aug 28, 2004 2:34 pm

that would by 5.0 by the end of today, and 7.5 by tomorrow. OMG we might have a cat 5 hurricane here! No but really, I wouldn't be surprised if we eventually ended up with a minimal hurricane. Maybe even low cat 2.

Matthew5 · #98 Postby **Matthew5** » Sat Aug 28, 2004 2:36 pm

59 flight level winds is about 45 knot surface winds.

Based upon the explosive intensification of Gaston, we need a Hurricane WARNING at 5 p.m. for the SC coast for Gaston
