Someone correct me if I am wrong, But the wave is measure from high point to low point. I think you can half the number for surge and then there are other variables that depend on depth of water apporaching the beach and such that reduce it even further from that wave.

I work at a marina in the Palm Beach area, and the hotel buildings are unfortunately 100% jalousies. They held up quite well during , though under a dozen were blown off their hinges (the outer metal panels, none of the inner glass panels came out).
Suffice it to say, the carpet by the doors and windows were rather moist, the CAT2 winds were more than enough to blow the rain through two layers and into the rooms.

I had mentioned this earlier. A wave in the open ocean is not the same as a wave as it nears shore. I don't know how all the parameters interact, but this does not mean 50 ft waves coming near shore. This buoy is something like 75 miles from shore.

Paul Murphy on just reported 50 mph winds in Biloxi, and they expect 31 hours of Tropical Storm force winds. He's at the Palace/Paradise Casino (Sorry, didn't catch the name exactly) and it's garage is flooded out already.
Take care, Frank. Good news is that Steve Lyons just said you will only have hurricane force winds very briefly there.

BillD,
you are absolutely correct, but these waves could certainly reach 30-40' (holy moly man)....Those aren't waves, they're friggin tsunamis! One on top of the other...

Correct. While storm surge can effectively push the shoreline far inland, the tremendous waves you see offshore just won't make it inland. In order to have 50-foot waves, you must have at least 50 feet of ocean below. For instance they built the Bahia Honda bridge (part of the overseas highway leading to Key West) 30 feet above sea level -- since the water is no deeper than 30 feet in that channel, it is presumed that waves could never crest over the bridge.
So yes, a 15-20+ foot storm surge will be devastating, and a few more feet of wind-produced waves can be expected to lash at anything just out of reach of the surge. There will NOT however be any colossal tsunami-like waves inland.

Green lightning is probably power transformers blowing.

Blown transformers, I saw ithe safe effect when went over New Smyrna. Because of the clouds and rain it lights up a large area. They'll be blueish green flashes.

Cindy,
Those are transformers blowing up. I saw the same thing in Orlando - they looked more blue to me, but you might have more rain which makes them look green.

That would be transformers shorting out Cindy. Already 15,000 without power in Mobile. Ours has been flickering, but still up. Going out any minute though !!

LOL, nice group effort everybody!
We had our share of 'Green Lightning' during too. Unfortunately, the local power utility stopped their preventative tree-trimming program a few years back for *ahem* budgetary reasons. There are still something like 100,000+ people going on two weeks without power (yes, they lost it a full day before the storm hit).
They didn't shut down the grid either, so there was a near-constant array of green-blue flashes as the winds picked up. Some heads are going to roll over there once things settle down

How often is it that someone throws a question out here and we get 4-5 exact same responses...A LOT...that's what makes so valuable...I could never have answered that question but obviously those who have been through it can!
Not necessarily what you wanted to hear, but at least there's no discrepancies! Keep it up, you guys rock!

The latest radar image looks like a jog eastward. Does anyone else see this or are these images starting to play mind games with me? :?:

cindy,
I found this on the Weather Corner
http://ggweather.com/wx_corner.html
"Q. During our recent spectacular lightning show I noticed that sometimes there was a greenish tint to the lightning. Can you explain this? Lucy Baldwin - Palo Alto
A. Clouds often take on a greenish hue before severe storms, but this is most often associated with hail. Hail is usually part of a thunderstorm. These tall, dense cumulonimbus clouds often block most of the sunlight, so the greenish tint may be a reflection of Earth's green foliage. However, the cause of the green tint has not been proven conclusively."
or it might be power lines...
