Ike was much more powerful than Katrina. Cyclone categories are based on maximum wind speeds but better measurements of power now exist and are used by some. Dr.Master's gave more accurate warnings as usual including this aspect. The good news is that Dr.M thinks we'll have another week of quiet. I-93 did form within the Caribbean, but wind shear is challenging its development.
More Cape Verde-type storms are possible, but not for a while. Now is not the time, but in the near future - Texas really may need to consider requiring stronger building codes on coastal counties. This couple lost their home to Rita, but had a contractor replace it with one built to take one virtually anything nature can dish out.
I'm sure that builder can write his own business ticket now...!
