City battered by rain as storms across the state trigger floods, a mini-tornado in Chester Hill and hamper Covid vaccine deliveries

Swathes of suburban Sydney were on alert for dangerous flooding after the city's main dam spilled over on Saturday, with severe storms across New South Wales also triggering a mini-tornado, evacuations, and hampering coronavirus vaccine delivery.

Warragamba Dam spilled over at about 3pm on Saturday and daily rainfall records for parts of the mid north coast for March were broken by more than 100mm.
