Prepping for Irma

All the weather talk the last few days has been about Hurricane Irma, which is a Category 5 hurricane with 185 mph winds as of the 2017-09-05 2100Z update.

Irma becomes only the fifth Atlantic basin hurricane with a peak wind speed of 160 kt or
higher.  The others are Allen (1980), the Labor Day Hurricane of 1935, Gilbert (1988), and Wilma (2005).

Still a little early to know what kind of weather to expect from Irma in South Carolina, but it looks like Florida will have a good chance of taking a big hit.

The intensity forecast shows some weakening over the next few days as Irma plows through the islands. Irma is still going to pack a pretty big punch when it reaches Cuba and Florida though.
