Just within about 3 weeks time – a different experience and perspective – not only in the locations of landfall, but also in the characteristics of two different hurricanes. While the September 13th Hurricane Florence was like a nasty sluggish monster – yesterday's Hurricane Michael was like a heroic monster in its wind power and storm surge. The former showed the power of relentless rainfall poured by a weak crawling storm. The latter is an example of the power of very high sustained wind speed of a fast-moving hurricane – let us say, in its grandeur like the utterance of Julius Caesar: Veni Vidi Vici.
We can describe both the storms in all different attractive terms in an attempt to make a serious subject lighter – but the misery of the affected people, damages and destruction are very real and painful. We feel their pain deeply and our thoughts and prayers are for the victims. Fortunately for the Florida Panhandle region however, the piling of storm surge by the landfalling (October 10th, 13:30 ET) Hurricane Michael came about 2 hours before the high tide (at about 15:10 ET at Apalachicola). This time-difference has likely abated the peak surge somewhat – yet strong enough to cause extensive coastal flooding with the surge force uplifting and carrying boats, homes, cars and debris like toys.
Let's continue the conversation, comment and get the best of us in these sad times.Regards,
Mr. Khan –
The following sentence in your 10-13-2018 ASCE Collaborate article caught my attention:
"Efforts of these officials resulted in the insertion of a "code within the code," called " High Velocity Hurricane Zone, HVHZ", applicable only in Dade, Broward, Monroe and Palm Beach counties of the State of Florida."
Just wanted to point out that per the FBC, the HVHZ has always consisted of only two counties: Broward and Miami-Dade. If there is some other source that I am not aware of that incorporates Palm Beach County and Monroe County in the HVHZ, please let me know.

Well said @Ramses Sanchez . I've grown and raised in the Caribbean as well like you (Dominican Republic), and despite being a third world country it is clear that Reinforced Concrete is the way to go. Personally the Eye of Hurricane George CAT 4 almost CAT 5 pass by my town and absolutely nothing happen to my house.
I understand the lobbism of the wood industry in the U.S. but seems like we as engineers are looking for an excuse to make wood construction better instead of cut to the chase and use concrete for everything, not only the foundation but walls, floors and more importantly the ROOF. The technology is there to analyze and design any type of concrete construction and the materials as well. Now it is doable and aesthetic is not a problem, because you can do concrete roofs any shape, pitch, form, in fact the more folded the better. A monolithic structure is the solution. I have been doing hundreds of those concrete roofs and concrete shell structures structural designs in the U.S. for various residences and affordable housing as well and it is possible and the ROI is very fast, sometimes less than 5 years and after that it's all savings. Really there is not an excuse, it is up to us to move ahead and lead by example, the solutions are out there waving at us since a long time ago.
