Season overview:
cyclone season in the north indica 2010

Cyclone Phet (IMD designation: ARB 02 , JTWC designation: 03A ) is the second strongest tropical cyclone ever recorded to form in the Arabian Sea - only cyclone Gonu achieved a greater intensity in 2007. The third named storm of the cyclone season in the Northern Indies 2010 initially moved in a north-westerly direction towards Oman , but was gradually caught by the westerly wind zone and deflected to the north as it approached the Arabian Peninsula . Phet crossed the east of the country and reached Sur in the Gulf of Oman , where he turned east. The cyclone moved parallel to the Pakistani coast and developed into a depression. South of the 15-million-inhabitant metropolis of Karachi , Phet finally moved overland on June 6th around 4:30 p.m. and dissolved in the late evening of June 6th.

The name of the cyclone was proposed to the WMO / ESCAP Panel on Tropical Cyclones of Thailand . Phet ( Thai เพชร ) means diamond .

Storm course

Train

Early on May 30, both the India Meteorological Department (IMD) and the Joint Typhoon Warning Center (JTWC) reported that a tropical depression had developed about 925 km southwest of Mumbai , India. In this low pressure area, there was a loosely organized convection that gathered around the circulation center in the monsoon trough. The system was located south of a high pressure area over Oman and was under the influence of moderate vertical wind shear . In the morning of the next day the convection around the center of the circulation had further consolidated, so that the JTWC drew attention to the fact that a tropical cyclone had formed. At the same time, the Regional Specialized Meteorological Center (RSMC) classified the low pressure area as a depression and added the warnings to the system. During the course of the day, the JTWC also began issuing storm warnings and classified the system as cyclone 03A because the convection had further consolidated despite the moderate wind shear.

After the vertical wind shear subsided in the early hours of June 1, the IMD determined that the depression had intensified into a cyclonic storm and named it Phet . After the system reached one-minute winds corresponding to Category 1 on the Saffir-Simpson Hurricane Wind Scale , the JTWC reported that Phet had begun a rapid intensification . During the course of June 2nd, the JTWC determined that this intensification Phet had continued and reached category 4 with one-minute winds of 230 km / h. The IMD, which as the RSMC responsible for the Indian Ocean, is commissioned by the World Meteorological Organization to monitor tropical weather conditions, uses a different wind scale based on three-minute continuous wind speeds. During this intensification phase, the IMD Phet gradually increased from cyclonic storm to severe cyclonic storm and then to very severe cyclonic storm.

The cyclone reached the coast of Oman northeast of Masira on June 4th. The center of Phet moved north along the coast and reached Sur on June 5, across the waters of the Gulf of Oman . Captured by westerly winds, the storm was deflected to the east. Higher wind shear prevented the hurricane from intensifying again over the open water of the Arabian Sea, especially since the hurricane moved eastward, closely parallel to the Balochistan coast. As a result, the storm was downgraded to a tropical depression.

Preparations

The map shows the amount of precipitation along the path of the cyclone using TRMM data.

Warnings of storm surges and high waves as well as wind warnings were issued for the coasts of Oman as well as Sindh and Balochistan in Pakistan including Karachi and the Indian state of Gujarat. The fishermen were told not to go out to sea. Pakistani meteorologists have warned of waves six to eight meters high that could flood parts of Karachi. For Balochistan, the meteorologists warned above all of flash floods . Experts pointed out that the sewers clogged with garbage and dirt in the metropolis of Karachi, which has a population of 15 million, cannot absorb the expected rainwater.

In Oman, the police ordered the immediate evacuation of Masirah and Ras al-Hadd . The loading of oil and gas was interrupted for a few hours before the arrival of the cyclone, as high waves prevent mooring and the loading facilities can be damaged as a result. Oman shipped an average of 731,000 barrels of oil per day in the first quarter of 2010 .

More than 8,000 residents of Kandla and Tuna in Kachchh District in Gujarat , India have been evacuated by the authorities.

Oman

Although Phet weakened significantly due to the effects of the coast, Phet still reached the Omani capital Muscat with gusts of wind of up to 200 km / h. 250 mm of precipitation fell locally, which led to flooding. The storm disrupted electricity and telephone connections. Many wadis became raging waters. Al-Amerat and Quriyat were hardest hit by the cyclone . In Oman, the effects of the cyclone killed 24 people, most of them drowned. The effects of the storm damaged bridges and roads, the seawater desalination plant, and electricity and water lines. The heavy rainfall flooded residential and business districts. The civil protection ministry put the damage to the infrastructure on June 7th at 780 million US dollars, the total insured damage in the private sector was estimated by the insurance company Axa at 100–200 million US dollars.

Pakistan

Heavy rainfall associated with the cyclone has already led to flooding in Balochistan as it approached the Pakistani coast. In Gwadar ten villages were flooded, the building of Radio Pakistan fell by the impact of the storm together. Road connections were interrupted. At least 15 people were killed in the effects of the storm in Pakistan.

India

The dissolving low pressure area led moist air to the north of India. In Rajasthan , heavy rainfall led to floods. More than 120 mm of precipitation fell in Jaisalmer . Several towns in the Jaipur district were flooded, the town of Lathi near Pokhran being hit hardest . 300 families were evacuated, 35 houses were washed away by the flood water.
