On one hand, the weather remains clear and dry during the day, while on the other hand, as the evening approaches, a drop in temperature is also seen. Meanwhile, the Meteorological Department has expressed the possibility of a cyclonic storm. According to IMD, the new weather system forming in the Bay of Bengal is becoming increasingly active and it may take the form of a major cyclonic threat in the coming days.

According to IMD, the low pressure area near Malaysia and the Strait of Malacca currently remains there and the cyclonic circulation associated with it is active up to a height of 7.6 kilometers. It is estimated that this system will move in the west-northwest direction and turn into a depression over the South Andaman Sea in the next 24 hours and after that it may intensify into a cyclonic storm over the South Bay of Bengal in the next 48 hours.

Heavy rain in next 5 days
Due to the effect of this cyclonic system, heavy rains are going to start in Tamil Nadu, Kerala, Lakshadweep and Coastal Andhra Pradesh in the next 5 days.

‘Who knows, Sindh may come to India again…’, Defense Minister Rajnath’s statement gave Pakistan sleepless nights.

Scenes of devastation are visible due to heavy rains in Vietnam. A large part of the country is in a state of ruin. Landslides, floods and rains have disrupted life. There have been 90 deaths so far. About 1 lakh 86 thousand houses have been affected. It is being told that 30 lakh cattle have been washed away in the flood currents. According to the report of ‘The Guardian’, there has been a loss of 2 billion dollars. Scientists say that the risk of disasters has increased since climate change.

Officials have confirmed that 90 people have died in this disaster. A large number of people are trapped on the rooftops and in the upper parts of the mountains. It has been raining in Vietnam since October. The situation in the south central areas is very worrying. Vietnam is a holiday spot, due to which the country has suffered economic losses worth crores of rupees. Here the government is providing all possible help to the affected areas.

The Environment Ministry here has said in its statement that out of 90 deaths, maximum 60 deaths have occurred in Dak Lak area. Flood has caused much devastation in this area. The government is keeping an eye on the situation, and is providing all necessary relief materials. At the same time, the local people have remembered the era of 1993. However, this time the situation is worse than before.

Never seen such destruction before..
The situation is so horrific that local people have told the media that the country has seen such devastation for the first time. One person told that when he recorded the highest water level, it reached only till his ankles. But now its range is one meter above. The situation is scaring every day. If the situation continues like this in the future, the country will face a food crisis.

In 2025, on one hand, Cyclone Montha is active in the Bay of Bengal, while on the other hand, Hurricane Melissa is also active in the Atlantic Ocean. Both are powerful ocean storms, which are creating destructive conditions like strong winds, torrential rains and possible floods. When a storm of wind rises over an ocean and starts tearing the sky with its speed, the question arises that what is its strength? This is not just a matter of fear or guesswork, but its strength is determined scientifically.

Every storm has its own ‘class’, which tells whether it is going to bring light rain or submerge the entire city. Let us know how the strength of a storm is estimated.

How to measure the strength of a storm

Scientists around the world use two major scales to measure the strength of hurricanes, the first is the Saffir-Simpson Hurricane Wind Scale, which is mainly applicable to the Americas, the Caribbean and the Atlantic Ocean. The second is the V-scale, which has been adopted in India, the Bay of Bengal and the Arabian Sea areas.

What is the Saffir-Simpson Hurricane Wind Scale?

This scale ranges from 1 to 5 depending on the maximum sustained wind speed of any storm. In Category 1, the wind speed is around 119 to 153 kilometers per hour, it can cause minor damage. In Category 2, winds reach 154 to 177 km/hour. In this, roofs can blow away, trees can break. From Category 3 (178–208 km/h) the damage becomes serious. Category 4 (209–251 km/h) and Category 5 (above 252 km/h) are the levels where everything turns into disaster. This scale not only gives an idea of ​​the speed of the wind but also its impact i.e. possible property damage.

Varicel used in India

The India Meteorological Department (IMD) uses the varicella scale to measure the strength of storms. This scale is also divided into five categories – from V1 to V5. V1 represents the mildest storm, while V5 is the most dangerous. Storms in the Bay of Bengal and the Arabian Sea are measured on this scale. The idea behind this is that the marine conditions and climate in these areas are different from those of the western oceans, so a different parameter was necessary to suit local conditions.

How are data collected

Scientists estimate the center of the storm and its wind speed with the help of satellite images, weather buoys and aerial surveys. The data received from radar shows the direction and speed at which the winds are moving. This data decides in which category the storm will be placed.

Cyclone Montha, formed in the Bay of Bengal, is rapidly becoming stronger and according to the Meteorological Department, it can turn into a severe cyclonic storm by the morning of 28 October.

The Meteorological Department has said that ‘during the next 12 hours, it is likely to move north-westwards over the south-west and adjacent west-central Bay of Bengal and after that it will move north-northwestwards and turn into a severe cyclonic storm by the morning of 28 October.’
