Heat alerts issued for NorthwestAn excessive heat watch is already in effect for portions of Washington, Oregon and California, and additional heat alerts will likely be added in the coming days as the incoming heat wave grips the region, the National Weather Service said. "Although this upcoming heat wave will likely not ultimately match the late June event in terms of magnitude, there is still an increasing probability of a prolonged period of potentially dangerous heat." In Seattle, high temperatures could reach the mid- to upper 90s beginning Wednesday or Thursday, likely breaking the record high for the day. The lack of significant cooling overnight could also make this heat wave more hazardous for this part of the country. Some cities may even break their daily record high temperatures.
