The Hebert Box was "discovered" in the late 1970s by Paul Hebert. This former NWS & NHC forecaster found many major Hurricanes that hit South Florida had to first pass through these boxes. The first box is located east of Puerto Rico and the second box is located over the Cayman Islands. Every Major Hurricane that passed through Box 2 late in the year, hit the Florida peninsula prior to 1950. Hebert says that a Hurricane does not have to pass through these boxes to hit, but if they do "you better pay attention". The 1935 Labor day Hurricane that devastated the Florida Keys developed west of this box and Hurricane Andrew passed NE of this box, so there are exceptions to the rule.
This image shows the two Hebert boxes. If Floridians want an indication of a possible hit they need to keep an eye on any hurricane that passes through these boxes. Nearly every major Hurricane that hit S Florida since 1900 passed through these boxes. When major Hurricanes miss these boxes,they virtually always miss South Florida. If a major Hurricane moves into these boxes South Florida really needs to watch out. These boxes approx 335 miles x 335 miles includes the Virgin Islands but not Puerto Rico. The pattern has proven accurate for 9 out of 10 storms storms that developed and hit Dade, Broward & Palm Beach Counties.
So what does all this mean when a Hurricane passes or develops in the Hebert Box #1 east of Puerto Rico since 1950?
1)N Carolina has as much of a chance to get hit as Florida.
2)20.58% or most go out to sea without hitting land.
3)Only 8.82% make it into the Gulf of Mexico when they pass through the box as a hurricane.
4)Puerto Rico will get hit 20.58% of the time (the highest outside of n Antilles).
What about Box #2,Hurricanes developing or moving through after Oct 1st since 1950?
Cuba & the Bahamas are at highest risk late in the season.
