1988

Of course, in 1988, Alberto didn't strike until August 7. There was no sign of Chris until August 21. So, while the hurricane season starts June 1, we should maybe not be expecting cyclones then. Wikipedia provides a list of Atlantic Hurricane Seasons. In 2000, the first three named storms (also Alberto, Beryl and Chris, as the NHC does not have ZipCar's commitment to unique names) were on the 3rd, 14th and 24th of August. In 2003, Anna formed April 20th, Bill and Claudette on June 29 and July 7th. By this time we were past Danny, and by the end of August to Grace. Last year, though, we were in Harvey by August and Lee by its end.

No real pattern leaps out, but we'll wait and see.
