I was trying to figure out your post #1032. It seemed that you were discussing minimum storm pressure (not wave height).
The pressure effects of a tropical cyclone will cause the water level in the open ocean to rise in regions of low pressure atmospheric and fall in regions of high pressure. The rising water level will counteract the low atmospheric pressure such that the total pressure at some plane beneath the water surface remains constant. This effect is estimated at a 10 mm (0.4 in) increase in sea level for every mb drop in atmospheric pressure. Normal atmospheric pressure is defined at 1013mb. Camille’s lowest recorded pressure was 905. So that’d amount to a little more than a meter in pressure surge around the region of lowest pressure. Gustov will be much higher than that.
The charts I posted are forecast swells+waves in excess of 20’ in areas (wind driven surge is much greater in magnitude than the pressure surge).
Tides are going to amount to about +0.5’ MSL between high and low tide at time of landfall; the area is very lucky in thatregard. Katrina made landfall with unusually high tides of several feet +MSL with just bonkers storm surge on top of that.
Thanks, just wanted to translate mb to baro units.
I think Gustavae is about 29.79 or so.
