TERRACE, B.C. -- Heat warnings are once again in place for Terrace and Kitimat -- and many other parts of the province -- as yet another heat wave is gripping BC.

Daytime high temperatures of 30 celsius are expected for North Coast Inland areas -- and it will be even hotter in the Lower Mainland, Sunshine Coast, eastern Vancouver Island and parts of the Interior, with Humidex values reaching into the low 40's in some of those areas.

And smoky skies bulletins remain up for much of southeastern BC and the Okanagan.

Public Safety Minister Mike Farnworth says Emergency Management BC is working with communities to ensure they have funding for measures such as cooling centres with targeted support for vulnerable people and overtime wages for staff.

Health Minister Adrian Dix is reminding everyone to be careful in the heat.

"If you or a loved one experience heat-related illness and you need help, please call 911 -- the BC Ambulance Service remains ready to serve you; paramedics and dispatchers are on deck to get help quickly to people," Dix told a news conference Wednesday.

Dix says there will be more staff in ER's to meet expected demand, and additional measures are being taken in hospitals to keep people safe.

Provincial Health Officer Dr. Bonnie Henry says the deadly heat wave in late June made officials realize the importance of sharing messages about the risks linked to extreme heat.
