A sea warning is likely to be issued on the Mid-Autumn Festival Sunday, forecasters said, adding that it remains uncertain if a land warning will be issued.
Regardless, moon watching in northern and eastern Taiwan could be affected, but the bureau said there remains a chance that you'll be able to spot a big full moon in central and southern parts of the country.
The bureau also warned people to avoid water activities in coastal areas during the holiday weekend as there could be high tides on the coastline.
