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.

Meteorological history

Late on November 4, 2009, the Joint Typhoon Warning Center (JTWC) reported that an area of convection had started to deepen around a poorly organized and elongated low level circulation center about 340 km (210 mi), to the southwest of Colombo in Sri Lanka. 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 vertical wind shear. 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. 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.

Later on November 9, the JTWC reported that the depression had intensified into a tropical cyclone, designating it as 04A, with wind speeds equivalent to a tropical storm as organized deep convection increased around a consolidating low level circulation center. Early the next day the IMD reported that the depression had intensified into a Deep Depression as convection organized further. The IMD further reported later that day that the deep depression had reached its peak windspeeds of 65 km/h (40 mph) 3-min sustained, which made it a Cyclonic storm with it being named as Phyan whilst located about 500 km (310miles) to the southwest of Mumbai as it moved into an area of high vertical wind shear. Early on November 11 the JTWC reported that Phyan had reached its peak intensity of 95 km/h (60 mph), before the Cyclone made landfall in Maharashtra between Alibagh and Mumbai later that morning. Later that day as the low level circulation center had rapidly detached from the deep convection the JTWC issued their final advisory whilst the IMD reported that Phyan had weakened into a depression before downgrading it to a well marked area of low pressure early on November 12.

Preparations and impact

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. Fishermen were advised not to venture into the sea along and off these coasts as the sea condition would be very rough.

Massive damage to property was reported in the districts of Ratnagiri, Raigad, Sindhudurg, Thane and Palghar. In Navi Mumbai the 7th one-day international cricket match between India and Australia was abandoned after Cyclone Phyan brought heavy rain to Mumbai.

As a tropical disturbance, Phyan caused heavy rainfall in Tamil Nadu. Kethi in Nilgiris district of Tamil Nadu recorded 82 cm of rainfall in 24 hours, beating the previous 24‑hour rainfall record for Tamil Nadu. Kethi recorded 1171 mm of rainfall in 72 hours, making it the 5th wettest cyclone in India.

Ketti which received 82 cm on November 8, 2009 (Depression ARB 03 or intensified Cyclone Phyaan) is the record holder for highest rainfall registered in 24 hours in Tamil Nadu

Previous Record holders — Orathanadu in Thanjavur district, which recorded 66 cm of rain on November 26, 2008 (Cyclone Nisha). In two days, Orathanadu registered 99 cm. 57 cm was registered by Cuddalore on May 18, 1943. On November 25, 1976, Nungambakkam in Chennai recorded 45 cm. On December 5, 1963, Nagapattinam registered 43 cm. Valparai in Coimbatore district received 36 cm on August 4, 2004 and Meenambakkam recorded 35 cm on November 25, 1976. Karaikal in the Union Territory of Puducherry registered 48 cm on November 15, 1991.

The death toll in rain-related incidents under the influence of the North East monsoon due to Depression in South Tamil Nadu rose to 77 in Tamil Nadu, with reports of seven more deaths.

Three deaths were reported overnight in Nilgiris, taking the death toll in that district to 40, police said here today.

One death each was reported from Villupuram, Tirupur, Erode and Cuddalore, they added. http://newstodaynet.com/newsindex.php?id=20128%20&%20section=6--
