Those years with no E. Pacific storm in June seem to be years in which a significant storm makes landfall. Obviously, the last time when no June storm occured, Camille devastated the Mississippi coast.

Here is a summary of years with no June storms:-

1969 - Camille CAT 5 Mississippi coast
1964 - Cleo CAT 4 Caribbean
- Dora CAT 3 Florida
- Hilda CAT 4 Louisiana
- Isbell CAT 3 Florida
1957 - Audrey CAT 4 Louisiana/Texas

These are the most recent years in which no storm has formed in the E. Pacific during June. The hurricanes listed above are shown by their peak intensity, although some did make landfall at this status. Looks like 2004 could be a big year in the Atlantic basin. Let's hope no-one gets hurt.
