Ten WA towns break heat records

Ten towns across WA have on Sunday broken their previous records for the hottest November day registered, the Bureau of Meteorology reports.

Norseman, in the state's Goldfields region, sweltered through 45.4 degrees, three degrees higher than the 42.4C it endured in 2007.

Salmon Gums, north of Esperance, followed with a top of 45.0 degrees, with Kalgoorlie (44.7), Mount Magnet (44.3) and Leinster (44.0) next on the list.

Laverton (43.4), Meekatharra (43.0), Newdegate (42.6), Lake Grace (41.8) and Jacup (41.1) reached moderately lower marks but were all still higher than the 40.4C registered on Perth on Saturday.

The capital's peak made for its hottest November day since records began in 1897.

The heatwave conditions have prompted total fire bans in most of the state, with several bushfire warnings issued throughout the day for a fire sparked near the Shire of Esperance town of Cascade.
