GLOBAL TROPICAL CYCLONE TRACKS - MARCH 1998
SOUTH INDIAN OCEAN (SIO) - South Indian Ocean West of Longitude 90E
NOTE: The tracking and intensity information for South Indian Ocean
Basin tropical cyclones is based upon operational warnings from
the Joint Typhoon Warning Center of the U.S. Air Force and Navy
on the island of Guam. The MSW are based on a 1-min averaging
period, which is used by all U.S. civilian and military weather
services for tropical cyclone warnings.

AUSTRALIAN REGION (AUS) - From Longitude 90E Eastward to Longitude 160E
NOTE: The tracks presented below are based on operational warnings
from the Australian Tropical Cyclone Warning Centre at
Brisbane, Queensland.
The MSW in the tables below are based on a 10-min averaging
period. To convert these to equivalent 1-min average winds,
multiply by 1.15. However, the wind speed estimates by
JTWC mentioned in the Remarks column, are 1-min average
sustained winds. To convert these to equivalent 10-min
average winds, multiply by 0.87.
JTWC = Joint Typhoon Warning Center, Guam, Marianas Islands
