There were six depressions tracked by the India Meteorological Department (IMD), which is the official Regional Specialized Meteorological Center for the northern Indian Ocean. The agency also tracked four cyclonic storms, which have maximum winds of at least 65 km/h mph on 5 sustained over 3 minutes. The American-based Joint Typhoon Warning Center (JTWC) tracked an additional storm – Tropical Storm Vamei – which crossed over from the South China Sea at a record-low latitude. The first storm originated on May 21, and became the strongest recorded storm in the Arabian Sea at the time. The IMD estimated peak 3 minute winds of 215 km/h mph on 5 while the storm was off the west coast of India. The storm weakened greatly before making landfall in Gujarat, and although impact on land was minor, it left up to 950 fishermen missing. A few weeks later, the first Bay of Bengal system originated – a short-lived depression that dropped heavy rainfall upon striking Odisha. After a period of inactivity during the monsoon season, there were cyclonic storms in September and October in the northern Arabian Sea. Both lasted only a few days and dissipated due to unfavorable wind shear. Another cyclonic storm formed in the Bay of Bengal and struck Andhra Pradesh, which dropped heavy rainfall that was equivalent to 300% of the average October precipitation total. The rains caused flooding, particularly in Cuddapah, where a dam was deliberately opened and inundated the town overnight. There were 153 deaths due to the storm and RS5 billion (Indian rupees, US$104 million) in damage. The final storm of the season tracked by the IMD was a short-lived depression in November in the Bay of Bengal. __TOC__ Season summary The India Meteorological Department (IMD) in New Delhi – the official Regional Specialized Meteorological Center for the northern Indian Ocean as recognized by the World Meteorological Organization – issued warnings for tropical cyclones developing in the region. The basin's activity is sub-divided between the Arabian Sea and the Bay of Bengal on opposite coasts of India, and is generally split before and after the monsoon season. The IMD utilized satellite imagery to track storms,World Meteorological Organization Annual Summary of the Global Tropical Cyclone Season 2001 2015-05-16 http://www.wmo.int/pages/prog/www/tcp/documents/doc/TD1132-TCseason2001.doc DOC and used the Dvorak technique to estimate intensity. Toward the end of the year, convection was generally lower than normal in the Bay of Bengal, despite being a typical hotspot for activity. There were no deaths or damage throughout the year outside of India, and damage there was lower than what occurred in the previous few seasons.

It moved eastward toward the coastline of southwestern India and rapidly intensified on May 22, strengthening from a deep depression to a very severe cyclonic storm within 24 hours. After approaching the coastline, the storm turned to the north and northwest away from land due to a ridge. Based on the well-defined eye and the storm's satellite presentation, the IMD estimated peak winds of 215 km/h mph on 5 on May 24, and the JTWC estimated 1 minute winds of 205 km/h mph on 5.Kenneth R.

On the same day, the JTWC issued a Tropical Cyclone Formation Alert, although they did not begin advisories due to the center being on the east side of the convection. At 0900 UTC on September 25, the IMD upgraded the system to a cyclonic storm, estimating peak winds of 65 km/h mph on 5.Kenneth R. Knapp Michael C. Kruk David H. Levinson Howard J. Diamond Charles J.

Around that time, the storm's outskirts dropped light rainfall in western India. Forecasters initially anticipated that the storm would strengthen to winds of 95 km/h mph on 5 and strike the southern Arabian Peninsula. However, persistent wind shear dislocated the circulation from the convection and imparted weakening. The IMD downgraded the storm to a deep depression and later depression on September 27, by which time the thunderstorms were rapidly dwindling. The JTWC issued their last advisory on September 28 after the circulation had no nearby convection. At that time, the storm was located 185 km (115 mi) east-southeast of Masirah Island off Oman. The IMD also downgraded the depression to a low-pressure area on September 28 and noted that the remnant system became poorly defined the following day.

It was associated with a circulation that moved westward from the Indian Coast,Gary Padgett Monthly Global Tropical Cyclone Summary October 2001 2001 2015-05-12 http://www.typhoon2000.ph/garyp_mgtcs/oct01.txt which formed as a well-defined low-pressure area over western India. The convection organized and increased, aided by low wind shear and good outflow. Late on October 8, the IMD classified the system as a depression, and early the next day upgraded it to a deep depression. A low-level circulation formed beneath a well-defined mid-level storm, with intense convection and strong winds north of the center. At 06:00 UTC on October 9, the JTWC began classifying the system as Tropical Cyclone 03A. With increasing banding features, the storm strengthened while moving west-northwestward, steered by a ridge to the north. At 09:00 UTC that day, the IMD upgraded the system to a cyclonic storm, estimating peak winds of 65 km/h mph on 5. Soon thereafter, the storm began weakening due to increased dry air and the upper-level environment becoming unfavorable. The thunderstorms diminished and disappeared over the circulation by October 10. That day, the JTWC discontinued advisories, and the IMD downgraded it to a remnant low-pressure area south of Pakistan. The storm brushed the Indian coast with rainfall, reaching 105 mm in on in Gujarat state, although there was no major damage.

However, the circulation remained removed from the deep convection. Early on October 16, the storm made landfall near Nellore, Andhra Pradesh. It quickly weakened over land, degenerating into a remnant low-pressure area over Rayalaseema on October 17. While moving ashore, the storm dropped heavy rainfall in Andhra Pradesh and extending into Tamil Nadu, causing flooding in some areas for the first time in 40 years. In a 24‑hour period, Sullurpeta recorded 261 mm in on of precipitation, and 13 stations recorded daily totals of over 100 mm (4 in); the highest two-day rainfall total was 676.5 mm in on, and some areas received 300% of the average October rainfall within 36 hours.International Federation of Red Cross And Red Crescent Societies India floods 2001 appeal No. 21/01 operations update No. 6 2001-11-09 2015-05-16 http://reliefweb.int/report/india/india-floods-2001-appeal-no-2101-operations-update-no-6 ReliefWeb Damage was heaviest in Andhra Pradesh, particularly in Nellore, Chittoor, and Kadapa, although floods also extended into Bihar. Several regional roads and rail lines were damaged, including portions of National Highway 5, which stranded hundreds of trucks; the routes were reopened within two weeks. The rains breached 1,635 water tanks, while 125000 ha acre on of crop fields, mostly rice and groundnuts, were impaired. About 1,000 head of cattle were killed as well. In Cuddapah, excess water was released from irrigation dams along the Buggavanka River; water levels rose 1.5 m ft on in the middle of the night, catching residents off guard, and damaging 18,244 houses. The dam was also breached in Nellore, and many towns in the region were inundated or isolated for two days. Across the state, the storm damaged 55,747 houses, accounting for RS5 billion (Indian rupees, US$104 million) in losses. There were 153 deaths related to the floods and the storm, mostly in Cuddapah.

Shortly after forming, the system moved northwestward and made landfall near Paradip, Odisha. It quickly weakened below depression intensity on June 13 while progressing inland, degenerating into a remnant low near Madhya Pradesh on June 15. The system dropped heavy rainfall along its path, with a daily peak of 350 mm in on in Vidarbha. On November 7, a cycling area of convection was persistent off the east coast of India, associated with a broad circulation embedded within a trough. The thunderstorms expanded and gradually organized, aided by good outflow and low wind shear.Gary Padgett Monthly Global Tropical Cyclone Summary November 2001 2002 2014-05-15 http://www.typhoon2000.ph/garyp_mgtcs/nov01.txt On November 11, the IMD upgraded the system to a depression off the coast of Tamil Nadu and Andhra Pradesh. On the same day, the JTWC began classifying the depression as Tropical Cyclone 04B. Located within a weakness of the ridge, the depression moved slowly to the north and northeast, and was initially expected to move ashore. However, increasing shear removed the convection from the center, and the storm remained offshore while weakening. On November 12, the IMD downgraded the system back to a low-pressure area. The storm brought rainfall to coastal portions of eastern India, peaking at 150 mm in on in Paradip. The near-equator Tropical Storm Vamei crossed Sumatra from the South China Sea at the end of December. According to the Japan Meteorological Agency – the official agency covering the western Pacific Ocean – the storm weakened into a remnant low on December 28, along the east coast of Sumatra. On the next day, the remnants entered the Bay of Bengal, and thunderstorms soon reformed over the circulation due to weak to moderate wind shear. After the remnants of Vamei regenerated, the JTWC classified it as Tropical Cyclone 05B on December 30, although the agency later treated it as a continuation of the original storm. Moving west-northwest, the storm re-intensified to a secondary peak of 65 km/h mph on 5. However, an increase in wind shear left the circulation center exposed. Vamei quickly weakened, dissipating early on January 1, 2002.Gary Padgett Monthly Global Tropical Cyclone Summary December 2001 2002 2014-05-15 http://www.typhoon2000.ph/garyp_mgtcs/dec01.txt dead https://web.archive.org/web/20130117014848/http://typhoon2000.ph/garyp_mgtcs/dec01.txt 2013-01-17 Kenneth R.
