Storm Kompasu to strengthen as it enters East Sea/South China Sea
NDO – In the next 24 hours, storm Kompasu is moving west-northwest rapidly at a speed of 20-25 kilometres
On the evening of September 30th, the Vietnam Meteorological and Hydrological Administration issued an alert regarding the movement and strength of Typhoon Krathon, a powerful storm that was posing risks to marine interests in the Northwest Pacific. According to their forecast, Krathon was located around 20.5 degrees north latitude and 120.5 degrees east longitude, just south of Taiwan, with maximum sustained winds of around 167-183 km/h (Category 5 super typhoon strength).
The typhoon was tracking west-northwest at 10-15 km/h and would likely bring its fierce winds and heavy rains into the northern region of the East China Sea over the following 24 hours. While not expected to directly impact Vietnam's coastal areas or mainland, Krathon's strong winds and high waves had the potential to affect shipping operations throughout the northern East China Sea and surrounding waters. Vessels sailing in the vicinity of the typhoon's eye and inner rainbands would face especially treacherous conditions.
As an avid weather observer and mariner myself, I always pay close attention to advisories regarding powerful tropical cyclones like Krathon. With winds equivalent to a Category 5 hurricane on the Saffir-Simpson scale, this typhoon packed immense destructive power and posed grave risks. Its location just south of Taiwan was also concerning, as a northwestward turn would bring Krathon very near one of the busiest waterways and shipping corridors in the world. Needless to say, knowing the precise track and intensity of such storms is critically important for avoidance of impacted areas by marine traffic.
Based on the forecast provided by Vietnam's meteorologists, Krathon appeared to be a formidable typhoon that demanded the utmost respect and precautions from those in its path or nearby. Satellite imagery at the time depicted a well-defined eye surrounded by a symmetric central dense overcast - hallmarks of an extremely dangerous cyclone. Streamlined outflow on the western side also hinted at exceptional upper-level divergence and the potential for rapid intensification. While some weakening was predicted 72-120 hours out as Krathon tracked further north and over cooler waters, it presented an acute hazard over those first few days.
The forecast winds and seas around Krathon were nothing short of punishing for any vessel caught directly in the storm's wrath. Gales extending 150-200 nautical miles from the center would have churned waves up to 7-9 meters high, completely disrupting maritime operations. Rogue waves breaking much higher were also a possibility given such a tight pressure gradient. Unsecured cargo on deck could easily be swept away, while green water regularly topside threatened to overwhelm even large ships. Helicopter rescues would be far too risky in such conditions. Any problems requiring emergency repairs may prove impossible to remedy at sea.
Of greatest concern were the projected winds of 150-165 knots near the typhoon's eyewall at the time of the forecast. Such violent gusts rank among the strongest ever observed globally and can cause catastrophic damage even to reinforced structures on land. At sea, they often spell doom for less robust vessels having no escape. Fallen masts and shredded sails are almost guaranteed, and the hull itself may not withstand the punishing assault. Aircraft are grounded below 30,000 feet in the typhoon's environs. The atmospheric turbulence generated by Krathon was truly immense and could catapult unrestrained items considerable distances.
Thankfully satellite imagery over the following days depicted Krathon tracking steadily further away from land as it accelerated toward the north-northeast. Some weakening did occur as colder waters sap its fuel supply. By the fourth day the system appeared much less symmetric and concentrated, the eye feature completely eroded. Winds dropped under typhoon force with the remnant low swinging well east of Korea and Japan. The threat had largely passed for coastal populations, though heavy surf and rough seas continued affecting offshore areas.
In closing, Typhoon Krathon offered another potent reminder of the immense destructive powers that can form in the tropical oceans. While not impacting land directly, its threat to maritime traffic and offshore energy/shipping interests was severe enough to warrant the highest vigilance and precautions from meteorological agencies and captains alike. Knowledge of tropical cyclone structure and behavior aids our preparations, though Mother Nature retains the final say. May this detailed look at Krathon help deepen weather awareness and encourage safe choices when tropical storms loom.
