    Re: Waterspouts.

    We get short-lived ones here in the Northumberland Strait from time to time.
    
    They are technically not the same as tornados.  Here is a nice summary of
    the phenomenon from Environment Canada:
    http://www.msc-smc.ec.gc.ca/cd/brochures/waterspout_e.cfm
    and
    http://www.msc-smc.ec.gc.ca/education/teachers_guides/module6_air_sea_intera
    ction_e.htmL? (The question mark should be in this URL, not out of it).
    
    "Waterspouts: These form occasionally over warm ocean water, particularly in
    the early fall when sea surface temperatures are still fairly warm, and
    colder air begins moving over marine waters. Fishermen working in the Gulf
    of St. Lawrence, for example, often report waterspouts in the early-mid
    fall. Colder air aloft is necessary to make conditions unstable enough for
    waterspouts to form."
