GLOBAL TROPICAL CYCLONE TRACKS - JUNE 1999
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
1-min averaging period, which is used by all U.S. civilian
and military weather services for tropical cyclone warnings.

NOTE: The tracking and intensity information for Northeast Pacific
Basin tropical cyclones is based upon operational advisories
from the Tropical Prediction Center/National Hurricane Center
in Miami, Florida, for systems east of Longitude 140W; and

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. In
a few cases the 10-min MSW given by PAGASA and JMA did not agree;
in those cases I reported the higher value. The estimates of
central pressure were obtained from JMA's advisories.
Some of the tracking information for Typhoon Maggie/Etang was
taken from warnings issued by the Royal Observatory of Hong Kong
(HKO), and the track for Tropical Depression Gening was based
in its entirety upon warnings from PAGASA. Michael V. Padua,
owner of the Typhon '99 webpage sent me the PAGASA, JMA, and
HKO tracks for these systems--a special thanks to Michael for
his assistance.

NORTH INDIAN OCEAN (NIO) - Bay of Bengal and Arabian Sea
NOTE: The tracking and intensity information for North Indian Ocean
Basin tropical cyclones is based primarily upon operational
warnings from the Joint Typhoon Warning Center of the U.S.
Air Force and Navy (JTWC) at Pearl Harbor, Hawaii. For weaker
systems not in warning status by JTWC, information gleaned from
the twice-daily issuances of the Indian Meteorological Depart-
ment (IMD) was used to complete the tracks. These bulletins
usually give analyzed center positions at either 0300 or 0600
UTC and 1200 or 1500 UTC.
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. For synoptic observations in the North Indian
region, both 10-min and 3-min average winds are employed, but
IMD makes no attempt to modify the Dvorak scale for estimating
tropical cyclone intensity; hence, a 1-min avg MSW is implied.
In the North Indian basin JTWC usually does not initiate warnings
until a system is well-organized and it is likely to attain
tropical storm status within 48 hours.
Windspeeds are usually not reported in the IMD bulletins. Systems
are usually classified as depressions, deep depressions, or
cyclonic storms. For depressions I assigned a MSW of 25 kts and
for deep depressions 30 kts. If the early stages of a system
were referred to as a low-pressure area, I assigned 20 kts.

Note: JTWC did not classify this LOW as a tropical depression, although
the 16/1800 UTC Tropical Weather Outlook indicated the existence of a
weak low-level circulation. The basis for the 30-kt MSW at 1200 UTC
is the fact that the IMD forecast referred to the system as a "deep
depression", which implies 30-kt winds.
