Tropical Storm Kim (1983)
Tropical Storm Kim was the only storm of 1983 to move from the Western Pacific basin into the North Indian Ocean basin as it moved across southern Indochina and into the Bay of Bengal as a tropical depression. Although Kim was a weak tropical storm, it still managed to cause 200 deaths and heavy crop damage in Indochina.
==Meteorological history==
Tropical Storm Kim originated a weak tropical disturbance that formed to the northeast of Truk on October 9. Over the next few days, the disturbance moved towards the west and was a persistent feature on satellite imagery; however, the disturbance showed no signs off developing and the Joint Typhoon Warning Center (JTWC) expected the disturbance to dissipate over the southern Philippines. On October 14, the disturbance moved into the Sulu Sea and subsequently it lost its convective signature and was no longer identifiable as a tropical disturbance, however the next day the system moved into the South China Sea and rapidly developed into a tropical depression. By this time, the monsoon trough was well developed in the South China Sea and provided a favorable environment aloft for further development.〔 By 1800 UTC on October 15, the Japan Meteorological Agency (JMA) first started monitoring the system.
Early on October 16, a Tropical Cyclone Formation Alert (TCFA) was then released as the JTWC expected Kim to intensify into a Tropical Storm within 24 hours.〔 The depression then intensified further and according to the Joint Typhoon Warning Center (JTWC), the depression attained tropical storm intensity at midday. However, the tropical storm was named ''Kim'' until several hours later, when the JTWC initialized warnings on the system.〔 Simultaneously, the JMA upgraded Kim into a tropical storm, with winds of , its peak intensity. Five hours later Kim made landfall on the coast of Vietnam while at peak intensity according to the JTWC.〔 The JTWC then stopped issuing advisories early the next day as Kim's atmospheric circulation had rapidly weakened over land, though intensity estimates from the JMA suggested that Kim was still a tropical storm.〔 Kim was then downgraded by the JTWC to a Tropical depression at 0600 UTC on October 17 whilst it crossed the border from Vietnam into Cambodia. After becoming even less organized, Kim was downgraded to a tropical disturbance by the JTWC.〔 On October 18, the JMA stopped watching the system.〔 Over the next couple of days the remnants of Kim moved across Indochina while producing a large amount of convection, while visual satellite imagery was showing indications that a mid to low level circulation center was apparent. Under than anticipation that the remnants of Kim would regenerate into the Andaman Sea, a TCFA was issued for the second time during the afternoon hours on October 18. Early the next day, the JTWC started to reissue warnings on Kim as it had regenerated into a tropical depression. Initially, Kim was expected to move across the southern tip of Burma and intensify further in the Bay of Bengal. Whilst Kim moved across southern Burma as expected, it never moved into the Bay of Bengal, instead Kim moved northwards along the coast of Burma, parallel to the Arakan Mountain Range and gradually weakened.〔 The JTWC issued their last warning on Kim at 1800 UTC on October 20 while located over the Arakan Mountains.〔〔
