CAT 5 Hurricane Dean - Archived threads

[brunota2003]

As of 7:40 UTC, the western edge of the eye is poised to come ashore. Should see landfall within the next 30 minutes or so.

[Normandy]

Wow.. that would mean total annihilation for anything in the path of those winds

Yes it would. However sustained winds like that prolly wouldn't last for more than one minute. The mean sustained wind in the northern eyewall of Dean seems to be 155 mph....with varied extended gusts up to 180 mph 60 min) and more intense bursts over 230 mph (less than 5-10 secs).

Also, chaser in Chetumal estimates winds outside to be sustained at 30 kts with 50 kt gusts.

Are the over 230's from ef5 tornados? cause that seems abnormally high.

Gusts within a hurricane this violent likely exceed 220 mph but ONLY in its northern eyewall and in VERY small streaks. Gusts in this hurricane are abnormally high because of the extremely intense convection. Hurricane Andrew produced very similar gusts (although none were recorded ove 200 mph)...however no wind istruments lived NEAR long enough to encounter Andrew's worst winds.

Look at the last 20 or so frames and tell me something didn't happen with the track of this storm. Before the eclipse, it was on a beeline for Chetumal (265-270 degrees track)

After the eclipse, it's heading on an almost 285-290 track. Quite the 'wobble'. I bet it saved Chetumal from a lot of damage and surge.

I don't know how to explain it... but it's there. Look for yourselves.

Wobbled right back into NHC track. Chetumal 15 miles maybe 20 south of southern eyewall.

Category 5 buzzsaw. We are watching history folks.

Yep on its present course Chetumal will miss the eyewall by 10 miles

[brunota2003]

As of 7:45 UTC NASA image, Eye coming ashore. The very western edge of it just touched land.
As of 7:55 UTC, expect a message from the NHC soon, western part of eye working inland. About 1/20 of the eye is over land.

[Normandy]

I am absolutely amazed by this storm.

its acting as if the Yucatan isnt even there. Truly specatucular case of a storm BOMBING while hitting land....havnt seen this since Andrew and Charley.

[typhoon_tim]

Just imagine if this happened 12 hours ago with more warm bath water ahead of it.... yikes.

I actually thing it hit at the perfect time....it would have been stronger *perhaps* but it would have DEF already began weakening if it was maxed out and not bombing.

[Sanibel]

[Coredesat]

Looks like they're making another run at the eye. In that case, I'll stay up a bit longer.

[Hockey007]

It was going to start a EWRC too, maybe 2 hours earlier though would have been more stronger imo, cause the intensification was going to continue for a while.

[NCSUwpack]

A guy on the radio is freaking out going crazy. He's saying there are no more trees... Then he gets cut off... Whoa.

[brunota2003]

Who would of thought, when Dean formed, it would turn into a monster that made landfall as a Category 5? I had a bad vibe about him, but definatly was NOT expecting this at all.

[brunota2003]

Landfall by 8:15 UTC. Eye working onshore, about 1/10 or so of it on.

WHAT?
What channeL?

And btw LOL this is astounding. Half of Dean is overland and he has maintained his impressive appearance. This is unreal.
