The BBC 24-hour forecast currently says Brighton and Hove will experience several hours of heavy snow tonight.
The forecast says snow will start falling at about 3am and could last well into tomorrow morning.
The city council’s gritters are out tonight once more. The last time the city experienced heavy snowfall in January, it brought widespread disruption.
More snow is forecast for Tuesday, Wednesday and Thursday.
The forecast on Windguru – a website popular with kitesurfers – also suggests snowfall overnight although the total is unlikely to exceed half an inch.
Windguru had predicted below freezing temperatures midweek, with steady snow looking likely.
Its revised forecast suggests milder tempeartures, with the wind likely to add a chill to the air, and a possibility of at least some snow.
