'''Cyclonic Storm Phyan''' developed as a tropical disturbance to the southwest of [[Colombo]] in [[Sri Lanka]] on November 4, 2009. Over the next couple of days, the disturbance gradually developed before weakening as it made landfall on Southern India on November 7. After the disturbance emerged into the Arabian Sea, it rapidly became more of a concern to the [[India Meteorological Department]] (IMD) reporting early on November 9 that the disturbance had intensified into a Depression, and designated it as Depression ARB 03 whilst the [[Joint Typhoon Warning Center]] (JTWC) issued a [[Tropical Cyclone Formation Alert]]. Later that day, the JTWC designated the system as Cyclone 04A. During the next day, the Depression turned towards the northeast the IMD reported that it had intensified into a Cyclonic Storm and named it as Phyan.

Late on November 4, 2009, the [[Joint Typhoon Warning Center]] (JTWC) reported that an area of [[Atmospheric convection|convection]] had started to deepen around a poorly organized and elongated [[Eye (cyclone)|low level circulation center]] about 340 km (210 mi), to the southwest of [[Colombo]] in [[Sri Lanka]].<ref name="STWA 04-11-09">{{Cite FTP |url=ftp://ftp.met.fsu.edu/pub/weather/tropical/GuamStuff/2009110418-ABIO.PGTW|title=Significant Tropical Weather Advisory for the Indian Ocean 2009-11-04 18z|date=2009-11-04|server=[[Joint Typhoon Warning Center]]|url-status=dead|accessdate=2009-11-10}}</ref> The low level circulation center was located in a region of upper level divergence which was providing a good channel for outflow, however it was also located in an area of moderate to high levels of [[Wind Shear|vertical wind shear]].<ref name="STWA 04-11-09"/> During the next couple of days the disturbance gradually developed whilst moving around a subtropical ridge of pressure before the disturbance moved onshore in India during November 7 and became more marked as it moved out into the warm waters of the [[Arabian Sea]] during the next day.<ref>{{Cite FTP |url=ftp://ftp.met.fsu.edu/pub/weather/tropical/GuamStuff/2009110518-ABIO.PGTW|title=Significant Tropical Weather Advisory for the Indian Ocean 2009-11-05 18z|date=2009-11-05|server=[[Joint Typhoon Warning Center]]|url-status=dead|accessdate=2009-11-10}}</ref><ref>{{cite web|url=http://weather.noaa.gov/pub/data/raw/wt/wtin20.dems..txt |title=Tropical Weather Outlook 2009-11-08 06z |date=2009-11-08 |publisher=[[India Meteorological Department]] |accessdate=2009-11-10 |url-status=dead |archiveurl=https://web.archive.org/web/20090717091810/http://weather.noaa.gov/pub/data/raw/wt/wtin20.dems..txt |archivedate=July 17, 2009 }}</ref><ref name="STWA 08-11-09">{{Cite FTP |url=ftp://ftp.met.fsu.edu/pub/weather/tropical/GuamStuff/2009110818-ABIO.PGTW|title=Significant Tropical Weather Advisory for the Indian Ocean 2009-11-08 15z|date=2009-11-08|server=[[Joint Typhoon Warning Center]]|url-status=dead|accessdate=2009-11-10}}</ref> Early on November 9, as a [[Tropical Cyclone Formation Alert]] was issued by the JTWC; the [[India Meteorological Department]] (IMD) reported that the disturbance had become a depression and designated it as Depression ARB 03 as multiple bands of deep convection had started to consolidate around the now well-defined low-level circulation center.<ref name="TCFA">{{Cite FTP |url=ftp://ftp.met.fsu.edu/pub/weather/tropical/GuamStuff/2009110909-WTIO.PGTW|title=Tropical Cyclone Formation Alert 2009-11-09 09z|date=2009-11-09|server=[[Joint Typhoon Warning Center]]|url-status=dead|accessdate=2009-11-10}}</ref><ref>{{cite web|url=https://listserv.illinois.edu/wa.cgi?A2%3Dind0911b%26L%3Dwx-tropl%26T%3D0%26X%3D558D791777B97BA4EA%26P%3D25681 |archive-url=https://archive.today/20240522073648/https://www.webcitation.org/5lAd1sXiS?url=https://listserv.illinois.edu/wa.cgi%3FA2=ind0911b&L=wx-tropl&T=0&X=558D791777B97BA4EA&P=25681 |url-status=dead |archive-date=2024-05-22 |title=Special Tropical Weather Outlook for the North Indian Ocean 2009-11-09 12z |date=2009-11-09 |publisher=[[India Meteorological Department]] |accessdate=2009-11-10 }}</ref>

==Preparations and impact==
{{Wettest tropical cyclones in India}}
As the IMD upgraded the depression to Cyclonic Storm Phyan, they warned the states of Gujarat and Maharashtra to expect extremely heavy rainfall of over 25 cm, (9.84 inches), over South Gujarat and North Maharashtra whilst squally winds of 70–75 km/h were expected along and off the coasts of Karnataka, Goa and Maharashtra.<ref name="Cwind 2009-11-10 18z"/> Fishermen were advised not to venture into the sea along and off these coasts as the sea condition would be very rough.<ref name="Cwind 2009-11-10 18z"/>

Massive damage to property was reported in the districts of [[Ratnagiri District|Ratnagiri]], [[Raigad District|Raigad]], [[Sindhudurg District|Sindhudurg]], [[Thane District|Thane]] and [[Palghar]].
