Statement as of 3:35 AM PDT on July 06, 2008
Expires 2:00 AM EDT on July 07, 2008
... Poor air quality expected under stagnant air this week...
... Hot temperatures will also return to northern California...
Strong high pressure will begin to build over the region
today and remain in place through at least Thursday. Light
northeasterly winds will shift smoke from area fires back into
the Sacramento and northern San Joaquin valleys the next several
days where it will remain trapped as upper level high pressure
builds over the area.
People are advised to limit outdoor activities and prolonged
exposure to the smoky air... especially those with respiratory
conditions... older adults and Young children. People with health
conditions that could be aggravated by the smoke and are concerned
about their exposure should be thinking now about how they may
avoid the smoke this week.
The strong high pressure may also bring the warmest temperatures
so far this year by Tuesday. While there is some uncertainty as to
how warm it will get due to smoke cover... record high temperatures
will be possible Tuesday through Thursday. High temperatures in
excess of 110 degrees may occur in the Redding and Red Bluff areas
during this period... with 105 to 108 degrees at Sacramento...
Stockton and Modesto. In the mountains... temperatures as warm as
90 degrees are possible up to 5000 feet. There is a risk of very
warm overnight temperatures Tuesday and Wednesday nights...
especially in the foothills east of Sacramento. Foothill
communities such as Auburn... Placerville... Grass Valley...
Paradise and Jackson may have overnight lows that remain in the
lower to mid 80s.
Stay indoors as much as possible during the peak heating of the
day. If you have to work or plan on any recreational activities
outdoors... drink plenty of water... wear light colored clothing
and take frequent breaks from the sun. Heat can affect anyone.
However... children... the elderly... people with medical conditions
and those engaged in strenuous outdoor activities will be the ones
most impacted by the hot weather.
