But it&#8217;s <strong>Tuesday and Wednesday<\/strong> that pose the biggest concern, when temperatures could soar to <strong>105\u00b0F (40.5\u00b0C)<\/strong> \u2014 well into the <strong>danger zone<\/strong> for heat-related illnesses.<\/p>\n<p>&nbsp;<\/p>\n<p>The <strong>NWS heat watch<\/strong>, in effect from <strong>Tuesday afternoon through late Wednesday evening<\/strong>, covers a large swath of <strong>Southwest Washington<\/strong> and <strong>Northwestern Oregon<\/strong>, including cities throughout the <strong>central Willamette Valley<\/strong>.<\/p>\n<p>&nbsp;<\/p>\n<p>\u201cThis level of heat would affect anyone without effective cooling and\/or adequate hydration,\u201d forecasters warned in a discussion released Friday. The concern isn\u2019t just about discomfort \u2014 it\u2019s about the real and rising risk of <strong>heat exhaustion<\/strong> and <strong>heat stroke<\/strong>, particularly for vulnerable populations.<\/p>\n<p>&nbsp;<\/p>\n<p>The warning area also includes the <strong>Columbia River Gorge<\/strong>, stretching into <strong>Corbett<\/strong>, <strong>Hood River<\/strong>, and down into the <strong>Lower Columbia<\/strong> and <strong>Cowlitz River valleys<\/strong>.<\/p>\n<p>&nbsp;<\/p>\n<p>With <strong>intense sunlight<\/strong>, <strong>dry conditions<\/strong>, and overnight lows offering little relief, the heat will linger well into the evenings. Health officials are urging residents to stay indoors during the hottest part of the day, <strong>stay hydrated<\/strong>, and <strong>check in on neighbors<\/strong>, especially the elderly and those without access to air conditioning.<\/p>\n<p>&nbsp;<\/p>\n<p>For those without A\/C, using <strong>fans to circulate air<\/strong> and <strong>keeping windows closed during the day<\/strong> may help prevent indoor spaces from overheating.
