The Bureau of Meteorology has resolved a major crash of its weather information operations after problems were detected early this morning.

A physical networking issue that was affecting its systems prevented updates to its website.

"The fault has been rectified and most services are now operating as normal," a statement uploaded to the bureau's website about 2:00pm (AEST) said.

"There may be minor delays in the upload of some data over the next few hours."

An earlier statement confirmed the system was experiencing problems.

"Forecasts issued on the bureau's website remain current," the statement said.

"The observations on the bureau's website, including radar images, are affected by the outage and are either not available or not current."

Temperature readings on the website were stuck at 6:00am, leaving many people and agencies reliant on the bureau's information in the dark, including radar imagery for vital airport services.

The BoM said contingencies were in place to communicate severe weather information.

This latest disruption to its services follows a major cyber attack on the bureau's computer network in early December, which also compromised sensitive systems across the Federal Government.

The bureau operates one of the country's largest supercomputers, providing critical information to a host of agencies including airports, shipping operators and fisheries.

It said it would provide updates on Twitter throughout the day as further information became available and systems were restored.
