What does record-breaking short-term heavy rain mean?

The Japan Meteorological Agency issued this notice when it saw and analysed short-term heavy rainfall that occurs only once every few years in that region. The criteria are normally calculated for each prefecture’s prediction region, using the first or second highest hourly rainfall data.

This information indicates that severe rain is pouring in the area surrounding the announcement, which might lead to calamities. Please follow the evacuation instructions provided by your local authorities and attempt to leave as early as possible.
