I see 10m wind height and 850mb wind height. A quick google search says that 850mb wind height is roughly the wind at 5000 feet. As a human that happens to live closer to 33ft (10m) as opposed to 5000 feet, when I look at those two maps and it shows wind speeds, it seems that the wind speeds for 10m height drop off really quickly after landfall. Is that actually right? I suppose the wind speeds at 5000 feet might be 80+ mph, but at ground level, is it really that much lower?

No, I'm not asking this in order to make a decision to evacuate or not (I'm not in FL). I suppose it is more idle curiosity. I've had some hurricanes skirt my area before. I'm about 25 miles inland in SC and curious what sort of wind someone would actually see at ground level from a (for example) Cat 1 coming onshore. Given what these maps are showing in Florida for Ian, it makes me wonder what sort of wind speeds someone in the middle of the state along the path would actual see at ground level.

Surface winds usually drop really quickly due to frictional effects even just a few miles inland.

Is the main concern for people that are 20+ miles inland TS force winds and the volume of rain?

To my eye, the eyewall on radar looks to be quickly melding with the new outer eyewall. Now we'll have to see if the outer eyewall begins to contract any.

Is it me or is the new eyewall starting to look a lot more robust on radar? Part of it could just be that I'm now looking at Radarscope on my phone; its color scale seems to run "hotter" than that of GR Level 3 on my PC.

I’ve found this site helpful in the past to see multiple tornado warnings on a map.

I'm as ready as I'll ever be so I hope this thing takes the southern solution and not come ashore in Englewood as Sarasota County usually gets trashed when that happens (nothing personal Lee/Collier bros).

Yeah, looks as though that EWRC may be finished in a couple hours. Doesn't seem to be disrupting too much for sure.

That's within the bounds of "reasonable" but don't forget about tornadoes and the associated effects of a major storm, like widespread power outages, traffic accidents, lack of clean water, etc.

Solid looking GOM storm. Now comes the tricky part, shifts and moves the next 8 hours. That will determine the landfall point and will make a huge difference in the surge if it slows down again.

Will this eleviate some of this pickup in strength? Also curious if shear will dwindle it before landfall, or is it almost for sure afterwards at this point....?

Considering this thing still is a Cat 3 and has a 947 mbar pressure (lower than before); yeah, not seeing anything major that could really stop this from really blowing up once the EWRC is done

Unless explicitly stated, all info in my posts is based on my own opinions and observations. Tropical storms and hurricanes can be extremely dangerous. Do not think you can beat Mother Nature. Refer to an accredited weather research agency or meteorologist if you need to make serious decisions regarding an approaching storm.
