The residents of Saint Martin’s Island in Cox's Bazar have begun to leave home for the mainland as Cyclone Mocha approaches the coast after turning into a very severe cyclonic storm.

The locals said more than 200 families moved to Teknaf from the island on Thursday and Friday, reports bdnews24.com.

Many Islanders took trawlers to Shah Porir Dwip in Teknaf on Friday to move to relative safety from the cyclone.

“We never left home during previous storms but the situation looks intense this year. Seven people from our family have moved to safety,” said Nur Jahan Begum, a resident of the island.

“There is a tendency among some residents of moving to a relative's house in Teknaf if such a storm signal is issued. But the number is not too high,” said Muhammad Kamruzzaman, the chief executive of the Teknaf Upazila administration.

He urged people to follow instructions while moving to safety instead of panicking. “We’ve prepared 17 storm shelters on Saint Martin’s Island. Hotels, resorts, schools and bungalows are also ready for evacuations.”

Cyclone Preparedness Programme teams, Border Guard Bangladesh, the Coast Guard, the navy, police and local government representatives and village police were put on high alert, Kamruzzaman said.

Mocha, which was centred about 1,000 km away from the coast of Bangladesh, intensified into a “very severe” cyclonic storm on Friday. The cyclone is likely to continue to move north-

northeastward on Saturday and intensify before crossing the coast between Cox's Bazar and Kyaukphyu Island in Myanmar by Sunday afternoon.

Heavy rains and thunderstorms are expected in the bay areas on Saturday evening as the cyclone hurtles towards the coasts. The lower lands at the coasts may experience 2-2.7 metres higher tides than usual, which could cause flooding.

Bangladesh raises cyclone warning to great danger signal 8

The Met Office has raised the storm warning steeply by four notches to great danger signal No. 8 for three seaports and 12 districts with very severe cyclone Mocha moving closer to the coasts. The three ports are Chattogram, Cox’s Bazar and Payra. Cox’s Ba

As a Bangladeshi, I feel proud of the civil defense involvement in the Cyclone Preparedness warning system developed and implemented in Bangladesh.

Thousands of lives have been saved using the warning system and evacuation processes.

EXPECTED LANDFALL: Tropical Cyclone Mocha is within 855 km from Myanmar, and the centre is expected to make landfall within the next 46 hour(s), along the shores of/near Chin, as a Category 3 hurricane, with sustained winds of about 194 km/h (ASEAN DMRS). According to JTWC, Tropical Cyclone MOCHA is expected to reach its peak at 220 km/h or equivalent to a Category 4 hurricane, just before making landfall on 14 May 2023.

194 kph is too fast. This speed will generate too strong a force or thrust on the walls and sloped roofs.

I fear too many damages on the path of this Mocha or what cyclone. Kaccha houses will get demolished and flown away.

However, continuous cyclones throughout many years have caused our people/ volunteers and others to become quite experts of tackling after effects of such cyclones.

President Biden was asking England to learn from BD only a few weeks before.

The main thrust of this cyclone will be borne by Rakhine state of Myanmar. Bangladesh's Cox's Bazar district will also get hit, especially St. Martin's island and Teknaf. We have already evacuated more than a million people to safe shelter. But Myanmar has a very poor capacity to respond in such a disaster. In 2008, a cyclone in Myanmar killed more than 85,000 people. Bangladesh also faced such magnitude of disaster in the past, but not anymore, thanks to our well integrated warning and evacuation program.

 

[-=virus=-]

In preparation for Cyclone Mocha, which is anticipated to hit on May 14 with wind speeds of up to 175km/h (108mph), thousands of individuals in Myanmar and Bangladesh are making arrangements to evacuate.

Cyclone Mocha LIVE: Cyclone Mocha same as category 1 Atlantic hurricane

Cyclone Mocha: Cyclone Mocha was gaining strength and set to intensify into a very severe cyclonic storm by Friday morning, packing winds of up to 135 kmph, and likely to move towards the Bangladesh-Myanmar coast, the weather office said on Thursday night.

www.livemint.com

apparently its the same as a Category-1 Hurricane (which is what they're known as in the Atlantic, and Typhoon in the far east)

shouldn't be too bad.

Here in Kolkata the cyclone is granting a temporary relief from heatwave going on since a month

While we have made tremendous progress in cyclone evacuation readiness over 30 years, this cannot be the ultimate solution. Displacement of homes and businesses is terrible for the economy. We need dedicated cycline-resistant building codes and infrastructure planning for coastal areas. Implementation will take decades since we are poor but we must start now.

We need dedicated cycline-resistant building codes and infrastructure planning for coastal areas. Implementation will take decades since we are poor but we must start now.

I have checked a few high-rise residential buildings to know what I will write below:

There are very few design offices in Dhaka and there is probably not even a single design engineer who is able to convert even the wind speed to FORCE in (kg/ m2) or in (pounds/ sq. feet or psf).

If the wind velocity is known, the design engineer would convert it to force. This value is multiplied by the surface area of the walls to get the total force.

This force acts to tilt or uplift a building/ structure causing its destruction. This calculated force is compared with the force created by an earthquake.

Usually, the earthquake force is larger than the wind force and is used to calculate the destabilizing force.

But, who do you want to design this kind of wind or earthquake-resistant structure? I have seen videos of Turkish buildings. No engineer there did design analysis.

Turkey and Dhaka are the same. Someone prepares drawings and a construction company builds a building.

Newly built Chittagong outer ring road is a dual purpose road built to protect the city from cyclone as well as to act as a bypass road. This road is built 33 feet above sea level, enough to protect from this type of severe cyclone. There is a plan to extend this coastal highway all along the coastline of Chittagong-Cox's Bazar from the Mirsarai economic zone to Cox's Bazar town, 250 km long. After completion, it will be able to protect a big chunk of our coastline from cyclone, will also protect the coastline against probable sea level rise. There is also a plan to build an elevated highway all along the entire coastline of Bangladesh in Noakhali, Barishal and Khulna region. Will act as a shield for Cyclone and probable sea level rise.

This is the first phase. Eventually a much higher storm surge bund (beri badh) about 50 feet high from sea level will be built (with a walk way trail on top) to prevent cyclone sea rise waves from breaching into inland areas.

You can't protect the cultivated areas from inundation during storms - but human settlements can be protected in certain areas. Building such bunds across wide swath of territory is an expensive affair.

Please ask the relevant govt offices to learn also the design of Sluice Gates that will be needed to supplement the construction of coastal Bunds you are proposing here.

There are hundreds of rivers/ canals that flow into the sea. If you build Bunds, but not sluice gates. The result is the influx of tidal waves into the farmlands via the open rivers.

So, the Bunds become useless and water flows upstream through the canals.

I am not so worried about the structural integrity of primary structures (i.e., beams, columns, load bearing wall, etc.). Building compliant to the regular building code should be able to keep standing through a cyclone. My concerns are related to:
1. secondary/tertiary elements of buildings (e.g.- canopies, windows, etc.) other pieces of infrastructure (electric poles, wiring, street lights, etc.) flying off and striking people and damaging other infrastructure.
2. Flood protection

Relevant codes, standards and regulations need to be tailored for coastal areas to minimise damage.

Mocha begins to lash coastal areas of Ctg, Barishal​

With a maximum wind speed of 210kmph, the cyclone is expected to cross Cox's Bazar-North Myanmar's coast between 9:00am to 3:00pm

The peripheral effect of Cyclone Mocha has started over the coastal regions of Chattogram and Barishal divisions, according to the latest bulletin of Bangladesh Meteorological Department.

Cyclone Mocha is approaching the coastal areas of Bangladesh and Myanmar with a maximum wind speed of 210km per hour, said BMD.

According to the bulletin, the very severe cyclonic storm at midnight was centred about 490km south-southwest of Chattogram port, 410km south-southwest of Cox's Bazar port, 530km south of Mongla port and 460km south of Payra port.

It is likely to intensify further and move in a north-northwesterly direction and cross Cox's Bazar-North Myanmar's coast between 9:00am to 3:00pm today (May 14), according to BMD.

According to latest bulletin, the maximum sustained wind speed within 74km of the very severe cyclone centre at midnight was about 190 kmph rising to 210 kmph in gusts.

In its latest bulletin released early today, Indian Meteorological Department said Mocha will cross southeastern Bangladesh and north Myanmar today with a sustained wind speed of 180-190 km per hour gusting up to 210km per hour.

The maritime port of Cox's Bazar has been asked to hoist the Great Danger Signal 10, it said.

Besides, the maritime ports of Chattogram and Payra have been advised to hoist Great Danger Signal 8 while the maritime port of Mongla has been advised to hoist Local Warning Signal 4.

According to the bulletin, the coastal district of Cox's Bazar and its offshore islands and chars will come under Great Danger Signal no 10.

The coastal districts of Chattogram, Feni, Noakhali, Lakshmipur, Chandpur, Barishal, Patuakhali, Jhalakathi, Pirojpur, Barguna, Bhola, and their offshore islands and chars will come under Great Danger Signal No 8.
