At 3:00 a.m. on September 16 (Wednesday), the tropical low pressure developing in the South China Sea became Typhoon No. 11 (Knowle).

▼ Typhoon No. 11 Wednesday, September 16 at 3:00
Area of existence South China Sea
Size class //
Force class //
Move 15 km / h northwest west
Central pressure 1000 hPa
Maximum wind speed 18 m / s (near center)
Maximum instantaneous wind speed 25 m / s

Typhoon No. 11 will move westward in the South China Sea while developing slightly, and it is quite possible that it will land in Vietnam from Friday 18 to Saturday 19. In Vietnam and Laos, caution is required against heavy rains and storms . There is no impact in Japan.

This year, the area of the sea where the sea surface temperature is high has spread to the north, and even on the Honshu coast, the sea surface water temperature is close to 30 ° C, which which is exceptional heat. In general, typhoons are likely to develop when the sea surface temperature is around 28 ° C or higher, and Typhoon No. 10 is expected to move north as it strengthens its power.

Also, if conditions such as weak winds in the sky overlap, there is a chance that power will not be lost like a normal typhoon even just before landing in Japan and in some cases approaching and landing in the peak state. developmental. That is also possible.

▼ Forecast 4 days after September 5 (Saturday) 21:00
Area of existence Near the sea near Daitojima South
Very strong force class
Move north-northwest 20 km / h
Central pressure 940 hPa
Maximum wind speed 45 m / s (near center)
Maximum instantaneous wind speed 65 m / s

Typhoon No. 10 has a large forecast circle, but this does not indicate the size or strength of the typhoon, but the uncertainty of its course.

Comparing the positions using simulation results calculated by meteorological institutions around the world such as Europe and the United States, there is a wide range of possible trajectories for Typhoon No. 10, from those that are oriented towards the Kinki region to those that are oriented towards Okinawa and Amami. I get it.

It is important to consider all the possibilities and prepare for the worst case scenario for each region, as the impact on each region will vary greatly depending on the course.

As of today (Tuesday), there are many simulation results that suggest that “very strong” forces will reach the shore.

The central pressure is about 930 hPa, which can approach the coast of Japan, and if that happens, it is comparable to typhoons that caused catastrophic disasters such as “Second Typhoon Muroto (925 hPa on landing)” and “Typhoon Isewan. (929 hPa when landing) “. Be.

Also, Typhoon No. 21 from 2018 that landed in Japan with the strongest force in recent years had a central pressure of 950 hPa at the time of landing. At the time of this typhoon, the city of Kansai, like the city of Osaka, was hit by a storm with an instantaneous maximum wind speed of around 50 m / s, causing enormous damage from storms such as the roof flying and the car overturning. The record tide caused damage to the Kansai International Airport and the coastal area of the city of Kobe.

We recommend that you take steps like cleaning things that are easily ruined and purchasing the necessary equipment at an early stage. However, the quantity of products is limited, so avoid unnecessary purchases and buy as many as you really need.

Typhoon number in normal years

Typhoon No. 11 is the second typhoon to occur in September. The average number of typhoons in September is 4.8, which is an average or slightly slower pace.

This year, the total number of typhoons that occurred until July was two, which was very small, but in August there were seven typhoons that exceeded the annual average, so although the rate of occurrence is slow, we cannot be alert.

As fall deepens, there is a chance that more typhoons will approach the mainland due to pressure distribution. Recheck preparations for heavy rains and storms caused by typhoons.

As for the names of typhoons, 140 names proposed by the member countries of the international organization “Typhoon Committee” are prepared in advance and given in the order of appearance.

Typhoon No. 11’s name “Noul / 노을” was proposed by North Korea (Democratic People’s Republic of Korea) and is derived from the word for “sunset”.
