Oh my god. Even though the long holiday is just starting, a typhoon is approaching.
What concerns me most is which way this typhoon goes over the next few days.
So I was looking at the typhoon track forecast released by the Japan Meteorological Agency（気象庁）.
This chart is often shown on the weather news, so many people see it.
It can be found on the website, and I found it useful to look at it in detail.
So I want to share it with you.
In this chart, the current center of the typhoon is marked with an X, and it is surrounded by a red circle and a yellow circle.
These circles represent the current storm area and the strong wind area, respectively.
And the biggest concern for many people is probably the future movement of the typhoon.
Namely, the area surrounded by the white and red lines.
The area surrounded by the white line is the forecast circle.
It reflects the possible range of the typhoon's center, with a 70% probability.
And the area surrounded by the red line is the storm warning area.
It reflects the possible range of the storm area over the next five days.
Please note that these areas don't reflect the actual size of the typhoon itself.
They are only probability indicators.
And here's something new I learned.
On the website, I found a button that shows the details of this probability.
If you select the middle toggle labeled "probability of entering the storm area," the details of the probability are represented by purple, red, and yellow ranges, split at the 30% and 70% cutoffs.
Moreover, if you tap a region, you can see how the probability of being in the storm area changes over the coming days.
This information would be useful for planning your schedule, so give it a try.
