Signal number 10 means wind speed of 89 to 102 km per hour.
As the cyclonic storm ‘Biparjoy’ rising from the Arabian Sea is gaining momentum, the threat to Gujarat is increasing. The storm is expected to hit Dwarka, Kandla and Jakhau Ports by Wednesday evening or night. At this time the storm is moving at a speed of 8 km per hour.
Due to this, 10 no. signal has been issued. Signals from number-5 to number-8 have been issued in other coastal areas. However, many people may not know what these signals are and how they work in the face of danger.
12 number signal means everything is over
Different numbers of signals have been installed at different places according to the prevailing gale force winds. Signals in maritime areas are numbered from 1 to 12. Whereas, the last number 12 signal means a storm coming at a speed of 119 to 220 km, which destroys everything that comes in its grip.
Different numbers of signals are set up at different places according to the prevailing gale force winds.
Fishermen also travel according to these signals
Actually, these signals are known as Beaufort scale, they were installed during the British period. In 1805, the British yacht officers decided these signals on the basis of the speed of stormy winds. Most of Gujarat is bordered by the Arabian Sea. Due to this you can see these signals everywhere in the coastal areas. Fishermen also decide how far to go into the sea on the basis of these signals.
