UPDATE: FIREFIGHTERS in the southwest Victoria are fighting strong winds and heat on two fronts.

CFA deputy incident controller Andy Cusack said services would be stretched as fires continued around the state, the Herald Sun reports.

"We'll be ramping up resources considerably over the next few days . . . but trying to pull resources is problematic," Mr Cusack said.

Firefighters from South Australia have been deployed throughout Victoria.

He said the current situation was still "a lot better than predicted".

"Our main concern is the wind," he said.

"It's been unpredictable. If we get what's forecast then we predict more movement of fires."

The 7050ha blaze at Drik Drik, about 400km southwest of Melbourne near the South Australia border, is expected to continue throughout the week.

People that do not have a bushfire survival plan have been told to consider leaving.

Some residents near Dartmoor and Drik Drik have already collected their belongings and fled their bushfire-threatened homes.

Dartmoor Hotel owner Lorraine Lipscombe said this morning most of the town - population about 200 - decided to leave rather than defend their properties.

"There's not a lot left in the town at the moment," Ms Lipscombe said.

The pub, 10 minutes from the Drik Drik fire, is preparing food for the 400-plus fire crews as they battle the blaze.

"The catering pulled out so we're doing it all," she said.

"All morning we've been making steak and egg sandwiches."

Meanwhile, searing conditions in the north of the state mean a severe fire danger rating along the South Australian border, along the Murray River and the border to New South Wales.

Temperatures in the north are expected to pass 40C, with parts of the state hitting 33C before 9am.

Yarrawonga, near the New South Wales border, hit 33.5C at 8.35am.

Rutherglen, in northeastern Victoria, was 34.1C just after 9am.

Today Melbourne is expected to reach a top of 31C.
