Cyclone Biparjoy grows stronger, approaches Pakistan's coastline

• Section 144 remains imposed on Karachi beaches.
• Fishermen continue going to sea, despite ban.
• Country's weather also impacts flight operations.

The Pakistan Meteorological Department (PMD) Sunday warned that a Very Severe Cyclonic Storm (VSCS) Biparjoy is gaining strength and has now turned into an Extremely Severe Cyclonic Storm (ESCS) in the Arabian Sea moving northward in the last 12 hours.

The cyclone now lies near latitude 18.1°N and longitude 67.5°E at a distance of about 760 kilometres south of Karachi, 740 kilometres south of Thatta and 840 kilometres southeast of Ormara.

According to Dr Sardar Sarfaraz, the chief meteorologist of PMD in Sindh, the cyclone system will maintain its northward trajectory. Maximum sustained surface winds are 150-160 kilometres per hour with gusts 180 kilometres per hour around the system centre within and sea conditions are phenomenal around the system canter with maximum wave height 35 to 40 feet.

"The favourable environmental conditions (sea surface temperature of 30-32°C, low vertical wind shear and upper-level divergence) are supporting the system to maintain its intensity," the PMD statement read.

The statement further mentioned that under the existing upper-level steering winds, the ESCS Biparjoy is most likely to track further northward until the June 14 morning, then recurve northeastward and cross between Keti Bandar (Southeast Sindh) and Indian Gujarat coast on June 15 afternoon as a VSCS. PMD’s cyclone warning centre, Karachi is continuously monitoring the system and will issue update accordingly, it added.

The weather in the port city will likely fluctuate between 35°C to 37°C, while the minimum temperature will be 29°C. However, the mercury is expected to rise up to 40°C on Monday.

At present, the level of humidity in the city’s air is at 76%, while winds are blowing at a speed of five kilometres. Overall the weather is expected to remain hot and humid in the next 24 hours.

There is a chance of rain with strong winds and thundershowers in Southeast Sindh, the Met Office said. During this time, winds can blow at a speed of 60 to 80km per hour.

Owing to the cyclone's threat, the Karachi administration imposed a ban on entering the city's beaches for fishing, swimming, sailing and bathing effective from today (June 11) till the "end of the storm."

The decision was taken to avoid any untoward incident of shipwreck or drowning. However, despite the ban, people are still fishing at the beach and fishermen were also present in the sea with their boats.

Meanwhile, fishermen of Ormara have also been advised to stay away from the sea from today till June 17, while citizens have also been prohibited from picnicking near the sea, the provincial fisheries department said.

Possible impacts

• With its probable approach to the southeast Sindh coast, widespread wind-dust/thunderstorm rain with some very heavy/extremely heavy falls accompanied with squally winds of 80-100 kilometres per hour likely in Thatta, Sujawal, Badin, Tharparker and Umerkot districts during June 13-17.
• Dust/thunderstorm-rain with few heavy falls and accompanied by squally winds of 60-80 kilometres per hour likely in Karachi, Hyderabad, Tando Muhammad Khan, Tando Allayar, Mirpurkhas districts from June 13 and 14 to 16.
• Squally (high-intensity) winds may cause damage to loose and vulnerable structures (katcha houses).
• A storm surge of 3-3.5 meters (8-12 feet) is expected at the land falling point (Keti Bandar and around).
• Fishermen are advised not to venture into the open sea till the system is over by 17 June, as the Arabian Sea conditions may get very rough/high accompanied by high tides along the coast.
