    Monthly Tropical Weather Summary
    NWS National Hurricane Center Miami FL
    800 AM PST Sun Dec 1 2019
    For the eastern North Pacific, east of 140 degrees west longitude:
    One tropical storm (Raymond) and one tropical depression (Twenty
    One-E) formed in the basin in November.  Although the long-term
    average is one tropical storm forms in the basin every second or
    third year, this is the second straight November with at least one
    named storm forming.  In fact, named storms have formed in November
    in five of the past six years.
    Overall, the 2019 eastern Pacific hurricane season featured near
    average activity.  There were seventeen named storms, of which seven
    became hurricanes and four became major hurricanes - category 3 or
    higher on the Saffir-Simpson Hurricane Wind Scale.  This compares to
    the long-term averages of fifteen named storms, eight hurricanes,
    and four major hurricanes.  There were also two tropical depressions
    that did not reach tropical storm strength.  In terms of Accumulated
    Cyclone Energy (ACE), which measures the strength and duration of
    tropical storms and hurricanes, activity in the basin in 2019 was
    a little below the long-term mean.
