WEEKLY TROPICAL CYCLONE SUMMARY #98: JUNE 13 - 20, 1993
North Atlantic Basin:
Tropical Storm Arlene: Tropical Depression Two formed near 21N 92W on 18
June. The system moved erratically northwestward and reached tropical storm
intensity the next day. Arlene reached a peak intensity of 35 kt with a min-
imum pressure of 1000 mb measured by reconaissance aircraft on several diferent
occasions on 19-20 June. (This is subject to revision. A reconaissance aircraft
reported a pressure of 996 mb at 0919 UTC 20 June just as the storm was making
lanfall. Comparison of the aircraft data to a nearby buoy suggests the aircraft
pressure was at least 2 mb too low. The exact pressure at that time is still
under investigation.) The storm continued a general west-northwest track until
it crossed the Texas coast south of Corpus Christi on 20 June. At the end of
the summary period, Arlene had weakened to a tropical depression over land and
was drifting west with 30 kt winds. This system affected Texas, Louisiana, and
the Yucatan Peninsula of Mexico. An automated buoy (42002) recorded 33 kt sus-
tained winds at 0600 UTC 19 June. Several oil rigs located further away from
center (and with anemometers 30-80 m above sea level) reported 35-45 kt sus-
tained winds with gusts as high as 55 kt. The minimum reported pressure was
1002.1 mb at the Kingsville, Texas Naval Air Station at 1300 UTC 20 June.
Rainfall totals are still incomplete. Corpus Christi reported a storm total of
9.21 in (234 mm). Other locations in southern and eastern Texas had between
10-15 in (254-381 mm). No rainfall reports have recieved from Mexico at this
time. The heavy rains caused damage to south Texas agriculture, but no monet-
ary figures are available at this time. There are no reports of casualties at
this time.
Eastern North Pacific Basin (E of 140 Deg. W):
Hurricane Adrian: At the start of the summary period, Adrian was drifting
west-northwest with 45 kt winds. Adrian continued its west-northwest track on
14 June, then it turned northwest on 15 June as it reached hurricane intensity.
Adrian reached a peak intensity of 75 kt later that day. Adrian turned north on
16 June as it weakened back to a tropical storm, then it stalled near 15N 119W
on 17 June while rapidly weakening to a tropical depression. Adrian then
drifted erratically southeastward and dissipated near 14N 118W on 19 June.
Tropical Storm Beatriz: Tropical Storm Beatriz formed very rapidly from
an area of disturbed weather near 14N 96W on 18 June. Moving northwest, the
system reached a peak intensity of 55 kt as it was moving inland into Mexico
the next day. Beatriz continued northwest and dissipated over land on 20 June.
The storm brought tropical storm force winds to the Mexican coast near Hua-
tulco and heavy rains to much of south central Mexico. There are no land sta-
tion reports available from the landfall region, but a ship reported west winds
of 54 kt and a pressure of 1000 mb just south of the center during landfall.
There are no reports of damage or casualties at this time.
Central North Pacific Basin (180 Deg. W to 140 Deg. W): No tropical cyclones.
Western North Pacific Basin (W of 180 Deg. W):
Tropical Storm Koryn: Tropical Depression 6W formed near 5N 156E on 15 June.
Moving initially west-northwest, the system turned northwest on 17 June as it
reached minimal tropical storm intensity of 35 kt. This intensity was main-
tained through the rest of the summary period. Koryn turned west on 18 June and
maintained a general westward track through the end of the summary period. Al-
though Koryn passed through the Caroline Islands, there are no reports of dam-
age, casualties, or significant weather at this time.
Tropical Depression 7W: Tropical Depression 7W formed near 10N 130E on 17
June. Initially moving west-northwest, the system turned northwest the next
day. TD-7W moved west-northwest across the Philippine Islands on 19 June, and
it dissipated over the South China Sea near 16N 118E on 20 June. Maximum sus-
tained winds in this poorly organized system were estimated at 30 kt. There
are no reports of damage or casualties at this time.
North Indian Ocean Basin:
Tropical Depression: The Indian Meteorological Department designated this
system a tropical depression over the extreme northern Bay of Bengal near 22N
88E on 17 June. Moving north and then north-northeast, the system made land-
fall in Bangladesh the next day. The system continued north-northeast and dis-
sipated over eastern India on 19 June. This system was more of a monsoon de-
pression than a true tropical cyclone as surface data indicated a broad center
with strongest winds in the southwesterly flow well removed from the center.
Chittagong, Bangladesh reported sustained winds of 35 kt at 0600 UTC 18 June,
and this is belived to be the peak intensity of the system. Ishurdi, Bangla-
desh reported a pressure of 987.7 mb at 0000 UTC 18 June with Dhaka, Bangla-
desh reporting 987.6 mb 12 hours later. There are no reports of damage or
casualties at this time.
South Indian Ocean Basin (W of 135 Deg. E): No tropical cyclones.
South Pacific Ocean Basin (E of 135 Deg. E): No tropical cyclones.
