OZONE ACTION! DAY DECLARATIONS

SOUTHEAST MICHIGAN
An Ozone Action! Day advisory HAS BEEN ISSUED for Thursday, June 20th!


WEST MICHIGAN
An Ozone Action! Day advisory HAS BEEN ISSUED for Thursday, June 20th!


The sting of summer will arrive in harmony with the calendar announcement 
of  the season.  Strong ridging of high pressure cell over the mid-Atlantic 
coast is forcing winds in the forecast region to back around to a southerly 
component.  Accompanying these winds are mostly clear skies and strong 
solar radiation as the sun reaches its northern most trajectory.

For Southeast Michigan, Wednesday will be a good "ramp-up" day as 
temperatures rise and winds shift southerly.  On Thursday, temperatures in 
the Detroit area are expected to approach 90 degrees with wind trajectories 
bringing in ample ozone building pollutants from the Ohio valley.  Combine 
the clear skies, hot temperatures, transported pollutants and Wednesday's 
ramp-up of background ozone, and Thursday provides itself as an excellent 
candidate for poor air quality.  As a result, Thursday has been declared an 
Ozone Action! Day for Southeast Michigan.

Forecasting West Michigan for Thursday has been more challenging.  Many of 
the mechanics which generate high ozone will be present such as hot 
temperatures, southwest winds causing transport from the Chicago area, and 
a build up of background ozone during Wednesday.  The fly-in-the-ointment 
comes in the form of a surface front dropping down from the northwest 
during Thursday.  The approach of the front will be late enough not to 
effect Southeast Michigan, but could provide early afternoon cloud cover in 
the western part of the state depressing higher ozone concentrations.  As 
many forecasters believe that the computer models are moving the front too 
quickly, a likely chance exists that the approaching cloud cover will not 
arrive in time to keep much of the western portion of the state from 
exceeding the 8-hour ozone standard.  As a result, Thursday has also been 
declared an Ozone Action! Day for West Michigan.

For the extended forecast, the passing front late Thursday or early Friday 
should relieve some of the high ozone concentrations during 
Friday.  However, the high pressure ridge will rebuild during the weekend 
and return the potential of hot temperatures and poor air quality.  We will 
review the most current model output Thursday morning and update this 
forecast at that time.

During the smog episode, individuals may experience eye
irritation. Heavy outdoor exercise may cause respiratory
symptoms such as coughing or shortness of breath. People
with heart or lung disease including asthma may experience
a worsening of their condition.

* A Smog Advisory means that there is a strong likelihood
that there may be poor air quality within the next 24 hours
due to ground-level ozone and particulate matter.

Spare the Air Actions

During a smog alert, there are a number of actions that you can
take to help spare the air.

Travel tips - all year round:
  - leave your car at home - walk, cycle, carpool or take public transit

    drive at moderate speeds


Health tips:

  - avoid exposure to vehicle exhaust fumes
  - avoid strenuous exercise in the heat of the day
  - consult your doctor for specific health advice

Electricity saving tips:
  -  save electricity at home by turning down the air
     conditioner and turning off lights you are not using
