Attention, please, everyone. We’ve accepted the
weather forecast on the radio this morning that
there will have a heavy rain tonight. Be sure
to shut the windows and doors until you leave
your classrooms. The sports meet when we planned to
hold it tomorrow will be put off. After it becomes
fine, we’ll make other announcement. We will
have classes on Wednesday as usually. Since it is
colder tomorrow, please dress on more clothes in time.
Those come to school by bike, don’t keep your
umbrellas open while riding.
