After a stretch of relatively mild build-up weather to start the school holidays, Katherine is bracing for a hotter change as temperatures reach past 40 degrees.
While risks of fire in Katherine remain very high this week, gusty winds are expected to ease off by the weekend.
"Very high to severe fire dangers will develop across the Gregory and Carpentaria Districts and the Top End, including Darwin's rural area from Wednesday," a Bureau of Meteorology spokeswoman said.
"This is due to the combination of temperatures in the high 30s to low 40s, relative humidity as low as 10 per cent during the afternoons (inland) and gusty southeasterly winds."
The Top End is likely to deliver a hot and sticky weekend with the return of humidity over the weekend, according to the bureau.
"Fire dangers will ease by the weekend as the winds become lighter, which means that sea breezes move inland earlier leading to the return of humidity for the Top End," the spokeswoman said.
The bureau's seven day forecast for Katherine will see sizzling temperatures reach 40 tomorrow, and 41 degrees by Saturday - where they are expected to stay.
