Today, October 14th (Tuesday), the Japan Meteorological Agency announced early weather information that temperatures from October 20th to 28th will be ``considerably low'' in Hokkaido and Tohoku,
while ``considerably high'' in Okinawa and Amami.



Looking at the weather map for the coming week, a low-pressure system is expected to rapidly develop and pass near Hokkaido from October 18th (Saturday) to October 19th (Sunday),
with the possibility of heavy storms and warning-level heavy rain mainly in northern Japan.

After this low pressure system passes, the area around Japan is expected to have a "high pressure pattern in the west and low pressure in the east."

There is strong cold air behind the low pressure system,
in the early part of next week, strong cold air is expected to flow into the skies over Hokkaido
, bringing snow on the flatlands.



On the 18th (Saturday), warm air will flow towards a low pressure system.
Any precipitation will likely turn into rain in many places.

However, on the 19th (Sunday), cold air is expected to flow into the northern Tohoku region, bringing snow on the
mountains with temperatures around 1,500 meters above 0c.

Furthermore, on Monday the 20th, cold air with temperatures below -6c will hit northern Hokkaido, bringing snow in the plains.

Since the beginning of this month,
cold air strong enough to cause snow to fall in the mountains of Hokkaido has flowed in several times,
but this is the first time that cold air strong enough to cause snow to fall even on the flatlands has flown in.
This season's first ``Winter General has arrived'' can be said.


The day before yesterday, October 12th (Sunday),
the highest temperature was recorded at 35.0c in Kimotsuki Maeda, Kimotsuki Town, Kagoshima Prefecture,
making it the latest "scorchingly hot day" in Japan, but
next week, winter air will suddenly arrive from the north.

It can be said that this year's "autumn" was quite short.

On the other hand, temperatures will continue to be high in Okinawa and Amami, and
in late October it is likely that some places will experience the highest temperatures in 10 years.

We continue to need to be careful about the heat in Okinawa and Amami.




Temperatures will continue to decline nationwide into next week.

In inland areas such as Asahikawa in Hokkaido, the forecast is for rain or snow from the 19th (Sunday).

The season will quickly progress into next week.
Please be careful not to get sick due to changes in temperature.
