WEEKLY TROPICAL CYCLONE SUMMARY #180 JANUARY 8 - 15, 1995

Possible Tropical Cyclone in the Mediterranean Sea: A low pressure system
formed near 38N 14E on 13 January. The system moved east through 14 January,
then it turned south on 15 January. As it turned, it took on the satellite
appearance of a tropical cyclone, including an eye embedded inside a well-
defined convective band. At the end of the summary period, the system was
drifting south along 20E west of the coast of Greece.

The exact structure of the system is uncertain. No upper air observations
are available near the center. Surface observations indicate air temperatures
of 45-60 F (7-16 C) along with sea surface temperatures of 51-62 F (11-17 C).
There is insufficient data to tell whether the system actually acquired full
tropical cyclone characteristics.

There are also no reports from close to the center once the eye formed.
During the initial development, ship DBBH reported 60 kt winds and a 992.7 mb
pressure at 0600 UTC 14 January and 58 kt winds and a 992.5 mb pressure 6 hr
later. Based on this and the satellite appearance, maximum sustained winds are
estimated at 65-70 kt (assuming that the system actually acquired full trop-
ical characteristics).

Tropical/subtropical cyclones are uncommon in the Mediterranean. Such
systems are known to have occurred in September 1947, September 1969, Janu-
ary 1982, and September 1983, and there are probably others that are less
documented. Further documentation can be found in an article by Rene Mayengon
in the Mariners Weather Log in 1984 and an article by Ernest and Matson in
Weather in 1983.

I've uploaded 2 gif and 4 jpg images of the system to anonymous ftp on
squall.met.fsu.edu in directory pub/jack. These are courtesy of the Meteosat-
5 archive at the University of Nottingham, UK. A special thanks to Jay Brei-
denbach of the NWS Office of Hydrology for alerting me to this storm!

North Atlantic Basin: No tropical cyclones.

Eastern North Pacific Basin (E of 140 Deg. W): No tropical cyclones.

Central North Pacific Basin (180 Deg. W to 140 Deg. W): No tropical cyclones.

Western North Pacific Basin (W of 180 Deg. W): No tropical cyclones.

North Indian Ocean Basin: No tropical cyclones.

South Indian Ocean Basin (W of 135 Deg. E):

Tropical Cyclone Christelle (TC-07S): At the start of the summary period,
Christelle was south-southeast of Mauritius, moving south-southeast with
35 kt winds. The system weakened steadily on 9 January, and it dissipated
later that day near 21S 57E. Although Christelle passed near Mauritius,
there are no reports of damage or casualties at this time.

Tropical Depression: A tropical depression formed on 12 January near 12S
131E, or just north of Darwin, Australia. The system drifted south into
northern Australia on 13-14 January. The system turned south-southwest over
land on 14 January, and at the end of the summary period it was continuing
this track over land. Maximum sustained winds in this system were estimated
at 30 kt.

Several stations in the Darwin area reported 20-30 kt winds and pressures
of 998-1000 mb. There are no reports of damage or casualties at this time.

South Pacific Ocean Basin (E of 135 Deg. E): No tropical cyclones.
