The '''1998 Andhra Pradesh cyclone''' was a weak but deadly tropical depression which impacted India, especially the state of [[Andhra Pradesh]], in October 1998. The eight depression and seventh deep depression of the [[1998 North Indian Ocean cyclone season]], BOB 03 developed from a low-pressure area in the Bay of Bengal on October 13. The next day, it made landfall near peak intensity. Rapidly weakening once inland, the depression dissipated the next day.

== Preparations and impact ==
Since the depression was weak when it affected land, it mainly produced heavy rainfall, which damaged croplands and property.<ref name="FE1">Ashok B. Sharma (October 19, 1998). Southern States Still Under Monsoon Spell. ''Financial Express''.</ref> Daily rainfall totals reached {{convert|110|mm|in|abbr=on}} in some areas, triggering flash flooding in areas previously affected by heavy rainfall. Due to the depression, the [[Kalingapatnam]] weather station recorded {{Convert|120|mm|in|abbr=on}} in rainfall on October 14, while the [[Avanigadda]] weather station recorded {{Convert|150|mm|in|abbr=on}} in rainfall on October 15.<ref name=":1" />

During the morning of October 14, the [[Srisailam Dam]] overflowed, inundating a nearby powerhouse and forcing officials to shut down the plant. The following day, the water level of the dam kept rising, causing nearly 53,000 residents in the area to be evacuated.<ref name=":0">Staff Writer (October 17, 1998).
