What is a flash flood watch?
A flash flood watch means the rain or conditions that lead to flash flooding are possible in the coming hours. Since 2022 most NWS offices issue a flood watch in its place: the national count fell from 692 in 2021 to 76 in 2022, while flood watches rose from 203 to 715 (IEM archive), so compare the two together. A watch means the conditions for the hazard are possible or favourable, but it is not yet happening: be ready to act if a warning follows. The national record · Every warning type in Indiana.
