Bengaluru (AP) — India and Pakistan braced for the first severe cyclone this year expected to hit their coastal regions later this week, as authorities on Monday halted fishing activities, deployed rescue personnel and announced evacuation plans for those at risk.

From the Arabian Sea, Cyclone Biparjoy is aiming at Pakistan’s southern Sindh province and the coastline of the western Indian state of Gujarat. It is forecast to make landfall on Thursday and could reach maximum wind speeds of up to 200 kph (124 mph), according to the Pakistan Meteorological Department.

Disaster management personnel have been deployed to densely populated regions and cities that will be in the storm’s path. The cyclone will likely affect Karachi in Pakistan as well as two of India’s largest ports, Mundra and Kandla, in Gujarat state.

Murad Ali Shah, the top elected official in Sindh province, visited the coastal areas and asked authorities to evacuate an estimated 80,000 people to safety.

At a meeting in Karachi, Lt. Gen. Inam Haider Malik, the head of the National Disaster Management Authority, was informed that the cyclone was located about 600 kilometers (300 miles) south of Karachi on Monday afternoon.

Sherry Rehman, minister for climate change and environmental coordination, said that all relevant departments of Sindh and Balochistan provinces have been placed on high alert. Pakistan’s Civil Aviation Authority asked airport officials to immediately take steps to ensure the safety of aircraft and cargo.

Biparjoy is the first severe cyclone to hit Pakistan since the devastating floods last year left 1,739 people dead and $30 billion in losses.

India’s army, navy and coast guard were assisting in preparations in Gujarat, the state’s Chief Minister Bhupendra Patel said in a tweet. Patel said people living in low-lying regions will be evacuated if necessary.

India’s Prime Minister Narendra Modi held a meeting with top officials to review disaster preparations.

Experts say climate change is leading to an increase in cyclones in the Arabian Sea region, making preparations for natural disasters all the more urgent.

“The oceans have become warmer already on account of climate change,” said Raghu Murtugudde, Earth system scientist at the University of Maryland. He said a recent study shows that the Arabian Sea has warmed up by almost 1.2 degrees Celsius (2.2 degrees Fahrenheit) since March this year, making conditions favorable for severe cyclones.

A 2021 study found that the frequency, duration and intensity of cyclones in the Arabian Sea had increased significantly between 1982 and 2019, he said.

U.N. climate reports have also stated that the intensity of tropical cyclones would increase in a warmer climate. A report by the Intergovernmental Panel on Climate Change in 2019 found that since the 1950s, the fastest sea surface warming has occurred in the Indian Ocean.

“In the age of climate change, natural disasters such as cyclones will only increase and cannot be avoided. Better preparation and better policies especially for South Asia’s large coastal cities such as Karachi, Mumbai, Dhaka and Colombo becomes all the more important now and can make the difference between life and death,” said Abid Qaiyum Suleri, executive director of Islamabad-based Sustainable Development Policy Institute and a member of Pakistan’s Climate Change Council.

Cyclone Tauktae in 2021 was the last severe cyclone that made landfall in the same region. That cyclone claimed 174 lives and caused damage of more than $1.57 billion.

The cyclone, named Biparjoy, is expected to make landfall on Thursday afternoon between Mandvi in Gujarat and Karachi in Pakistan with a maximum sustained wind speed of 125-135 km per hour, gusting up to 150 km per hour, the India Meteorological Department (IMD) said on Monday.

The weather office has advised fishing communities to halt operations and the evacuation of people from the coastal areas of Saurashtra and Kutch regions of Gujarat.

Two of India biggest ports – Mundra and Kandla – are in the Gulf of Kutch, while the Jamnagar refinery, the world’s biggest oil refinery complex owned by Reliance Industries (RELI.NS), is based in Saurashtra.

Seven teams of India’s National Disaster Response Force and 12 teams of State Disaster Response Force have been deployed in the districts likely to be affected by the storm, Gujarat Chief Minister Bhupendra Patel said in a Tweet.

Nearly a dozen districts in coastal Gujarat would be affected by heavy rainfall and gusting winds, although some of the districts are sparsely populated, which would limit the damage, said a weather office official, who declined to be named.

A 1998 cyclone killed at least 4,000 people and caused hundreds of millions of dollars in damage in Gujarat.

Biparjoy delayed the onset of the annual monsoon over the southern state of Kerala, but now conditions are favourable for the progress of much-needed rains in some more parts of Maharashtra, Karnataka, Andhra Pradesh and Tamil Nadu states, the weather office said.
