'''Cyclonic Storm Roanu'''{{#tag:ref|The name ''Roanu'' was contributed by the [[Maldives]]; it means [strong] in the [[Maldivian language]].<ref>{{Cite news |url=http://www.thedailystar.net/country/why-the-cyclone-called-roanu-1227571|title=Why is the cyclone called Roanu?|date=2016-05-21|work=The Daily Star|access-date=2016-05-23}}</ref>|group="nb"|name="Etymology"}} was a relatively weak [[tropical cyclone]] that caused severe flooding in [[Sri Lanka]] and [[Bangladesh]] during May 2016. It is the first tropical cyclone of the [[2016 North Indian Ocean cyclone season|annual cyclone season]]. Roanu originated from a [[low-pressure area]] that formed south of [[Sri Lanka]], which gradually drifted north and intensified into a cyclonic storm on 19 May. However, [[wind shear]] and land interaction caused it to weaken slightly, before reintensifying as it accelerated towards the coast of Bangladesh.

The storm was responsible for 201 deaths in [[Sri Lanka]] and another 26 deaths in [[Bangladesh]]. Damage throughout Sri Lanka reached US$2 billion. Roanu also brought torrential rainfall to the Indian states of [[Tamil Nadu]], [[Andhra Pradesh]], [[Kerala]] and [[Odisha]] as it drifted in a generally northeastward direction, close to the coast.

At the time, Roanu was tracking slowly northward along the northern periphery of a [[subtropical ridge]] located over the [[Malay Peninsula]]. Despite favorable outflow and warm [[sea surface temperature]]s (SSTs) reaching {{convert|31|C|F|abbr=on}}, its proximity to land and moderate vertical [[wind shear]] kept the storm from [[rapid intensification|intensifying rapidly]].<ref>{{cite web|title=Tropical Cyclone 01B (Roanu) Warning #04 |url=http://gwydir.demon.co.uk/advisories/WTIO31-PGTW_201605190300.htm |publisher=Joint Typhoon Warning Centre |access-date=19 May 2016 |url-status=dead |archive-url=https://www.webcitation.org/6hcWCzlVq?url=http://gwydir.demon.co.uk/advisories/WTIO31-PGTW_201605190300.htm |archive-date=19 May 2016 }}</ref> The [[diurnal temperature variation]] over land and the persistent wind shear began to affect the deep [[Convection (meteorology)|convection]] obscuring the [[Eye (cyclone)|low-level circulation center]] (LLCC). In the late hours of that day, Roanu showed a weakening trend after most of the convection covering the LLCC was sheared off. During that time, Roanu was located approximately {{convert|150|km|mi}} from [[Visakhapatnam]]. However, the wind shear soon decreased,<ref>{{cite web|title=Tropical Cyclone 01B (Roanu) Warning #07 |url=http://weather.noaa.gov/pub/data/raw/wt/wtio31.pgtw..txt |publisher=Joint Typhoon Warning Centre |access-date=19 May 2016 |url-status=dead |archive-url=https://www.webcitation.org/6hd2OkFGR?url=http://weather.noaa.gov/pub/data/raw/wt/wtio31.pgtw..txt |archive-date=19 May 2016 }}</ref> and the storm reestablished deep convection over and around the LLCC, forming a [[central dense overcast]] in a period of 6 hours.
