This hazardous weather outlook is for northeast and north central
Colorado.

.DAY ONE...This Afternoon and Tonight

Showers and isolated thunderstorms are expected this afternoon
south of a line from Grand Lake to Boulder to Limon. Some of
these will produce a period of heavy rain, up to an 1.5 inches in
an hour. This could produce minor flooding in areas that have
received heavy rain over the last few days. In areas further
north, including the Cameron Peak and East Troublesome burn areas,
there is just a chance of thunderstorms and the threat of flooding
will be lower. Some showers may linger from Park county onto the
plains south of Interstate 70 through the evening, but the threat
of heavy rain will be lower after sunset.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

Drier weather is expected Wednesday and especially Thursday,
though there will still be some afternoon storms over the
mountains with a low threat of burn area flooding. Some increase
in thunderstorm activity is expected for the weekend.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight. However,
any reports of heavy rainfall or flooding would be appreciated.

...OZONE ACTION DAY ALERT FROM 400 PM TUESDAY UNTIL 400 PM
WEDNESDAY...

The Colorado Department of Public Health and Environment has
issued the following...

WHAT...Ozone Action Day Alert.

WHERE...Douglas, Jefferson, Denver, western Arapahoe, western
Adams, Broomfield, Boulder, Larimer, and Weld Counties

WHEN...400 PM Tuesday August 16 to 400 PM Wednesday August 17

IMPACTS...Ozone Action Day Alert is now in effect for the Front
Range Urban Corridor. Requests to limit driving of non-ZEV
vehicles (i.e., gas or diesel) are now in effect until at least 4
p.m. Wednesday, August 17, 2022.  Air quality is expected to
remain in the Good to Moderate range on Tuesday. On Wednesday,
warm and sunny conditions will allow for Ozone development, and
concentrations are expected to reach the Moderate to Unhealthy for
Sensitive Groups Range. The highest Ozone concentrations are most
likely in the southern and western portions of the Denver Metro
Area, including Highlands Ranch and Golden.For areas included in
this advisory that are not expected to reach the Unhealthy for
Sensitive Groups (USG) air quality designation, we request that
activities, such as driving non-ZEV vehicles (i.e., gas or
diesel), be reduced to lessen the impacts on neighboring air
quality. Additional air pollution in this region may directly
worsen air quality or contribute to precursors which may also
adversely affect air quality.  For Colorado air quality
conditions, forecasts and advisories, visit:

HEALTH INFORMATION...Increasing likelihood of respiratory symptoms
and breathing discomfort in active children and adults and people
with lung disease, such as asthma. Active children and adults, and
