PUDDLE TIME: Four-year-old Maya Horton’s fairy wings drooped a little in yesterday’s rain in Darby Street, Cooks Hill. – Picture by Anita JonesCHRISTMAS in the Hunter is likely to be a wet one this year, experts say.

The Weather channel released early forecasts yesterday for the Christmas period.

Chief meteorologist Dick Whitaker said there could be rain along the entire NSW coast for Christmas.

‘‘It’s only an initial estimate and it could well change but we’re expecting temperatures to be a little bit below the average this Christmas,’’ he said.

The Hunter experienced heavy rain yesterday as a trough moved up from the south before heading out to sea.

Many streets on the Central Coast closed due to minor flooding.

Gosford received a whopping 124millimetres of rain by 9am yesterday, the heaviest December rainfall in 22 years.

By yesterday evening the State Emergency Service had received 250 calls for help from Central Coast areas, including six flood rescues, most who were people stranded in their cars.

The State Emergency Service dealt with 21 call-outs in the Hunter for leaking roofs, trees down or properties threatened by storm run-offs.

Mr Whitaker said heavy rain should start clearing up tonight.

But a senior meteorologist at The Weather Channel, Tom Saunders, said the dreary weather was far from over.

‘‘It’s still the coldest start to summer in 51 years and it won’t be warming up, with below average temperatures — in the low 20s — predicted for the next week,’’ he said.
