Severe Cyclonic Storm Herbert, known in the West Pacific as Tropical Storm Herbert and in the Philippines as Tropical Depression Neneng, was a moderately intense but long-lived tropical storm which affected the Philippines, Southeast Asia, and the Indian subcontinent during October 1983. The nineteenth tropical depression and eleventh tropical storm of the 1983 Pacific typhoon season as well as the sixth depression, fourth deep depression, second cyclonic storm, and first severe cyclonic storm of the 1983 North Indian Ocean cyclone season, Herbert developed from a weak area of convection east of Mindanao.

Subtropical cyclone

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

The origins of Herbert can be tied to a tropical disturbance which was first noted on 3 October as an area of convective activity located around 250 NM (460 km) east of Mindanao. Despite being unorganized, a weak surface circulation was discernible in the disturbance's synoptic wind field. As a result, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) designated the disturbance as a tropical depression later that day, naming it Neneng.
