Heat Advisory Extended Through Friday Evening as Napa Valley Hot Spell Grinds On

NAPA: The National Weather Service has extended its heat advisory for the Napa area through 10 p.m. Friday, adding another day to an October hot spell that forecasters have already stretched multiple times. The Tuesday morning update from the Weather Service shows the advisory running until 10:00 PM PDT Friday, Oct. 9.
The advisory took effect Saturday morning and was initially scheduled to expire Sunday, KION Central Coast reported. On Monday the Weather Service extended it through 10 p.m. Thursday, covering all nine Bay Area counties away from the immediate coast, and the Tuesday update pushed the end time to Friday evening for the Napa area.
Forecast highs near the Napa County Airport run around 93 degrees today, with 91-degree afternoons expected Wednesday and Thursday before easing to about 81 degrees on Friday, according to the Weather Service point forecast. Overnight lows stay mild, limiting relief from the daytime heat.
The cumulative heat impacts will continue and a moderate risk of heat-related illnesses continues into Thursday.

In addition to the heat, the Bay Area Air District has extended a Spare the Air Alert through Tuesday, Oct. 6, because of unhealthy concentrations of ground-level ozone. Officials said ozone can cause throat irritation, congestion and chest pain, trigger asthma and worsen bronchitis and emphysema, with young children, seniors and people with respiratory or heart conditions especially vulnerable.
How to handle the heat
Officials urge residents to drink plenty of water and bring water to people who are vulnerable when possible, wear lightweight and loose-fitting clothing, and limit strenuous activity to the early morning or evening. Drivers are reminded never to leave children or pets in unattended vehicles, where interior temperatures can turn lethal in minutes.
