The Monthly Tropical Weather Summary is issued on the first day of every
month during the hurricane season. It briefly describes the previous month's
tropical cyclone actvity and gives a table of basic meteorological statistics,
such as the dates of occurrence and estimated peak intensity, for all of the
season's tropical cyclones to date. Narrative summaries for individual cyclones
are no longer included as of 2009, although brief descriptions for records of
interest may be provided. 

Users requiring comprehensive information on each tropical cyclone including
synoptic history, meteorological statistics, casualties and damages, and the
post-analysis best track (six-hourly positions and intensities), are
encouraged to consult the end of season tropical cyclone reports. Atlantic
tropical cyclone reports are available at www.nhc.noaa.gov/2008atlan.shtml
and Eastern Pacific tropical cyclone reports are available at
www.nhc.noaa.gov/2008epac.shtml.

Atlantic Tropical Weather Summaries are issued under WMO and AWIPS header
ABNT30 KNHC and MIATWSAT. Eastern Pacific Tropical Weather Summaries are
issued under WMO header ABPZ30 KNHC and AWIPS header MIATWSEP.
