Clackamas County is investigating a possible heat-related death after the extreme heat event over the weekend.

Hurricane forecasts are now much more accurate, 20 years on — largely because of federal government research.

Multnomah County has declared a heat emergency as temperatures in the Willamette Valley and the Columbia River Gorge are expected to climb into the triple digits for several days.

The National Weather Service recently announced a La Niña watch. It's an early prediction, but if true, it could bring more rain and cooler weather to the Pacific Northwest.

Forecasts nudge Erin's likely path to the west, increasing the risks at U.S. beaches. Experts say the storm's massive size, rather than windspeed, is what makes it a threat.

Temperatures reached the high 80s Wednesday – but were much hotter the previous three days, with the official high peaking at 100 on Tuesday.

The National Hurricane Center expects the storm to strengthen over the next several days and says it could become a hurricane by late Thursday.

The National Weather Service projects temperatures to remain in the high 90s or above 100 in large swaths of Oregon on Tuesday before a big cool down.

Triple-digit temps are expected along both sides of the Oregon Cascades, and stretching east to the John Day Basin and Blue Mountains. In response to the heat, several counties are opening cooling centers.

The National Weather Service is forecasting temps nearing, and in some cases exceeding, 100 degrees.
