Liaison over rainstorm warnings will be reviewed after confusion arose about school closures yesterday.
The Education Department said it would confer with the Royal Observatory on warning procedures because of the confusion over the severity of the morning downpours.
Afternoon-session schools were closed although the storms cleared by lunch time.
The department did not make a decision until 10.30 am despite the red rainstorm warning being issued by the observatory at 7.05 am. The warning means 50 millimetres of rainfall is expected to fall within an hour.
Scores of confused parents called the department during the morning storms as most schools remained open. Morning-session students had to commute to school in the thundery conditions.
'The problem was the timing of the heavy rain which came when most children were already heading to school,' a department spokesman said.
