Part of the 1993 Pacific typhoon season

Severe Tropical Storm Lewis, known in the Philippines as Tropical Storm Huling[1], was a weak but deadly tropical cyclone which impacted the Philippines, South China, and Southeast Asia during July of 1993. The fourth named storm of the 1993 Pacific typhoon season, Lewis developed from a low-pressure area formed by a monsoonal trough near the Philippines during early July.

  Extratropical cyclone, remnant low, tropical disturbance, or monsoon depression

In late June 1993, a large monsoonal trough would extend from the Philippine Sea to Southeast Asia, spawning the precursor disturbance to Lewis in early July.[2] On 06:00Z on July 4, the Joint Typhoon Warning Center (JTWC) would begin to monitor the disturbance east of the Philippine Islands. Around two days later, the JTWC would issue a Tropical Cyclone Formation Alert (TCFA) on the system since its convection had improved, and on 00:00 UTC the next day, issue its first warning on the system as Tropical Depression 08W. Later that day, the depression would cross into the Philippine Area of Responsibility (PAR), resulting in PAGASA naming it Huling.[3]

The next day, the JTWC would upgrade the system to Tropical Storm Lewis, although in their post-seasonal analysis, they would state that Lewis became a tropical storm nearly 12 hours earlier.[2] On June 9, Lewis would exit the PAR.[3] Later that day, Lewis would enter the South China Sea.[4] Lewis would gradually strengthen, and on 00:00 UTC on July 10, be upgraded to a typhoon. Over two days later, the JTWC would issue their last warning on the system as it dissipated over Southeast Asia.[2]

Preparations edit

Hong Kong edit

On July 10, the Hong Kong Observatory would hoist its Stand-by Signal No. 1 as Lewis neared the island but would lower it a few hours later.[4][5]

Impacts edit

Philippines edit

In the Philippines, Lewis would cause 112 deaths and 75 injuries.[3]

Hong Kong edit

In Hong Kong, heavy showers associated with Lewis caused landslides in parts of the New Territories. Additionally, Lewis would produce gusts, peaking at 58km in Green Island Station.[5]
