GLOBAL TROPICAL CYCLONE TRACKS - JULY 1998
ATLANTIC (ATL) - North Atlantic Ocean, Caribbean Sea, Gulf of Mexico
NOTE: The tracking and intensity information for Atlantic Basin
tropical cyclones is based upon operational advisories from
the Tropical Prediction Center/National Hurricane Center,
located in Miami, Florida, USA. The MSW are based on a

NORTHWEST PACIFIC (NWP) - North Pacific Ocean West of Longitude 180
NOTE: The tracking information for Northwest Pacific Basin tropical
cyclones is based primarily upon operational warnings from the
Joint Typhoon Warning Center of the U.S. Air Force and Navy on
the island of Guam. Comparisons were made with track coordinates
given in advisories from the meteorological services of Japan
(JMA) and the Philippines (PAGASA). In general, whenever the
center position differed by more than 40-50 nm from JTWC's, an
entry was made in the Remarks column.
The 1-min avg MSW were taken from the JTWC advisories while the
10-min avg MSW were obtained from PAGASA's advisories if the
storm was in PAGASA's area of responsibility; otherwise, they
were gleaned from JMA's advisories or high seas forecasts. The
estimates of central pressure were obtained from JMA's advisories.
