It was equivalent to a strong Category 3 hurricane on the Saffir-Simpson scale at peak intensity.  The depression moved in a generally northwestwards direction without intensifying, and made landfall on India's Odisha coast, south of Puri, at about 15:00 UTC (20:30 IST) on July 18. 2,301 people were evacuated from their houses and 202,957 hectares (501,520 acres) of agricultural land were submerged. According to insurance broker Aon Benfield, Irma caused $30 billion in damage to the mainland U.S, and $20 billion in damage in the Caribbean. Initially tracking northwards, the system soon recurved towards the northeast before weakening into an area of low pressure early on October 22, while located over northeastern Bangladesh, Meghalaya, and southern Assam. , On October 18, the JTWC noted an area of thunderstorm activity located in the eastern Bay of Bengal as having a partially exposed low level center while located in a marginally favorable environment for further development. The record number occurred in the El NiÃ±o year of 1997, which had twelve Category 5 storms--ten of them in the Northwest Pacific, where most of Earthâs Cat 5s occur.  Admin.  It moved further north-northeastwards towards Gujarat coast and encountered cooler sea surface temperatures and dry air intrusion from the Arabian Peninsula and was last noted as a well-marked low-pressure area off the coast of Gujarat. This is the second longest period on record that an Atlantic hurricane has maintained that intensity, behind the 30 hours of Hurricane Allen of 1980. These almost-Cat 5s were Super Typhoon Lan in the Northwest Pacific (155 mph winds at 0 UTC October 21, 2017), and Hurricane Jose in the Atlantic (155 mph winds at 11 UTC September 9, 2017). The full line of A. O. Smith Cyclone® Mxi condensing water heaters have been designed to provide years of dependable service and feature industry leading technology. Maria weakened slightly as it powered through the Virgin Islands and Puerto Rico as a top-end Category 4 storm with 155 mph winds, causing catastrophic damage and at least 98 deaths. Below is a "rogue's gallery" of all three Category 5 storms from 2017: Cat 5 #2, Atlantic.  The system produced 40 knots winds in the western quadrant and the JTWC upgraded to a tropical storm. UPDATE: in post-season reanalysis, Noru was downgraded to a Cat 4, meaning that the Northwest Pacific had no Category 5 storms in 2017. The Northwest Pacific averaged 2.9 Category 5 storms per year from 1990 - 2017, including five such storms in both 2015 and 2016. UPDATE: in post-season re-analysis, Cyclone Ernie of April 2017, northwest of Australia, was re-analyzed to be a Category 5 storm, while Super Typhoon Noru was re-analyzed to have only become a Category 4 storm. The floods persisted in Bangladesh since a Deep Depression over Bay of Bengal made landfall and killed 156 people in Bangladesh.  An anticyclonic circulation lay over central India in the middle & upper tropospheric levels thus making the system move in a north-northwesterly direction. It mentions all of the season's storms and their names, duration, peak intensities (according to the IMD storm scale), damage, and death totals. Address SXM CYCLONE BP 1148 Marigot 97062 Saint Martin Cedex Sécurité civile. Moving northeastwards, it reached its peak intensity in the early hours of 16th. Very Severe Cyclonic Storm Ockhi formed in early December and wreaked havoc in the countries where it impacted.

Tue, 26 Sep 2017 19:04:00 +0200. We don't yet know what 2018 will bring our planet in the way of tropical cyclones, but a striking feature of 2017 was the relative lack of Category 5 storms globallyâonly three. A couple of depression formed between mid October and November which continued the rain spell causing destruction of life and property. Two tropical cyclones just missed achieving Category 5 status in 2017, topping out with 155 mph winds (157 mph winds are the threshold for a Cat 5). This season produced only three named storms, of which one only intensified into a very severe cyclonic storm. Thus, the total number of Cat 5s in 2017 remained at three.  In West Bengal, Halisahar recorded 189 mm. This map illustrates the tropical cyclone MARIA- 17 path with low, medium and strong wind impact zones observed and predicted at 18 September 2017. , A total of 31 people have been killedâ9 in Bangladesh and 1 in Myanmar and 19 in Manipur  During the next several days, the system moved into Bay of Bengal and slowly drifted westward, but the storm was unable to organize significantly, due to unfavorable conditions.  Moving nearly north-northeastwards, it intensified into a deep depression over north Bay of Bengal in the night of 11th (1800 UTC)and peaked with estimated 3-minute sustained windspeeds of 55 km/h (35 mph). Damage and death totals include the damage and deaths caused when that storm was a precursor wave or extratropical low, and all of the damage figures are in 2017 USD.  Under favorable conditions, rapid deepening took place, and the system was classified as a depression on April 15. A low pressure area formed over west central & adjoining north Bay of Bengal off north Andhra Pradesh south Odisha coast in the morning of June 10. It moved in a west-northwest direction until degenerated to a well marked low pressure area over east Madhya Pradesh during the next day.. Damage throughout all the affected countries totalled almost US$1.37 billion. International Hurricane / Cyclone / Typhoon Tracking Map. The following day, the system depicted flaring convection to the north of the low level circulation center. This story does not necessarily represent the position of our parent company, IBM.  Total losses were estimated at Rs 2187.2 million (US$34 million). We recognize our responsibility to use data and technology for good.

Cherrapunji received 320 mm rain in association with the system. Up to 25 blocks of eight districts in the state had received rainfall exceeding 135 mm (5 in), with the Kanas block of the Puri district recording rainfall of 274 mm (10 in). Only twelve Cyclonic Storms have developed over the Bay of Bengal this early in the year between 1891 and 2016. Climatologically, the formation of tropical cyclones in the Bay of Bengal at this time of the year is rare.  The Madden Julian Oscillation lay over phase 4 with amplitude 1 and these conditions helped in maintaining the intensity of the system and associated convection and thus the storm intensified further into a deep depression later on the same day. 3 as a result of the strong crosswinds and heavy rainfall. Warm sea surface temperatures and a pole-ward channel helped the system to consolidate, and on December 6, the IMD initiated advisories on Depression BOB 08, while the JTWC to issued a TCFA on the system, as it intensified to a deep depression. The most active basin in the year was the Western Pacific, which documented 27 named systems. The season officially had an early start compared with the last two seasons, with the formation of Cyclone Maarutha over the Bay of Bengal in mid-April.  An anti-cyclonic circulation lay to the southeast of the system centre leading to poleward outflow favouring genesis of the system. , On November 20, the remnant energy of Tropical Storm Kirogi led to the formation of a new low-pressure area over the Gulf of Thailand. The system moved fast under the influence of mid-latitude trough in westerlies lying over India in the middle and upper tropospheric levels and the anti-cyclonic cyclonic circulation lying to the northeast of the system. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. Irmaâs landfall intensity of 180 mph winds in the Leeward islands is second only to the 1935 Florida Keys Labor Day Hurricane as the highest landfall intensity on record for an Atlantic hurricane.  As the system moved over land, it weakened gradually into a depression over east Bangladesh & neighbourhood due to land surface interaction and thereafter into a well marked low pressure area. The season began with the formation Cyclone Maarutha on April 15 and ended with the dissipation of a deep depression on December 9. 5 (Maria in 2017).  The storm tracked westwards, and intensified further into a Severe Cyclone Storm, early on December 1. In addition, the town of Cherapunji in Meghalaya reported rainfall of 283 mm (10 in) â among the highest reported in association with the depression.  Two people were reported killed in Malda district of West Bengal..
