Move Northwest West 15 km/h
Central pressure 998 hPa
Maximum wind speed 18 m/s (near the center)

Observing future trends with large course errors

Since the wind that moves the typhoon is relatively weak, the error in the course forecast is very large. The size of the forecast circle five days ahead is very large with a radius of 650 km, which indicates that the error in the course is large, not the size and strength of the typhoon.

Typhoon No. 1 will gradually move northward over the next week, and it is highly likely that it will change its course to the northeast in the latter half of next week, which may affect the Daito Islands region of Okinawa, the Ogasawara Islands of Tokyo, and the Izu Islands. It is assumed.

Weekly weather forecast

Although it is unlikely that it will hit Honshu directly, the impact from the second half of next week is unclear, and it is undeniable that it may indirectly develop frontal rain clouds and be affected by strong winds and high waves. Please keep an eye on future trends.

The degree of development is still inaccurate, but Weathernews’ view is that it will become a force with a storm zone at the beginning of the week. The possibility of becoming a strong force cannot be denied.

The average number of occurrences in April is 0.6. Occurrences during this period are not uncommon.

Number of typhoons in normal years

Typhoon No. 1 is the first typhoon that occurred in 2022. This is the first typhoon in regarding four months since Typhoon No. 22 that occurred in December last year.

In the northwestern Pacific Ocean, the typhoon occurrence is the least in January to March, and the number of typhoons begins to increase gradually from around April.

Looking at the statistics for the past 10 years, it can be said that it is not uncommon for typhoons to occur during this period, as there were only two typhoons in the year when the number of typhoons was 0 by the end of April.

Another typhoon in the east of the Philippines

Apart from Typhoon No. 21, tropical cyclones are developing in the eastern part of the Philippines. The Japan Meteorological Agency has released information that this tropical cyclone is expected to develop into a typhoon within 24 hours. The next typhoon will be called “Typhoon No. 22”.

This tropical cyclone will move northward a little tomorrow (Tuesday), but following that it is expected to move westward to the South China Sea, so this will not affect Japan either.

Typhoon name

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

The name of Typhoon No. 1 “Malakas” is a name proposed by the Philippines and is taken from the word meaning “strong”.
