You have got to be kidding me.

The period for Joe's forecast to materalise has been and gone

Or does his forecast stretch out for months ahead ??

In that case, it's easy.

There will be storms anywhere from Channel Islands to Northern England,
sometime during the summer

There will be Hurricanes in the Atlantic between June and November

When someone makes a weather prediction, it MUST have an end date
applied

It's same situation with so called psychics, when they refuse to give a
real date for their predictions. "There will be a big Earthquake at
some point"

Where? When?

..... Silence - Cause they don't want to commit themselves
