According to unverified air pollution data,
Michigan's Thumb at Harbor Beach, MI had the worst
ozone air pollution in the Eastern United States
yesterday.

Harbor Beach showed 3 hours over the old health
standard of 125 ppb, one hour average.   The highest
measured concentration was 152 ppb, one hour average.

All but two air quality monitors in Southeastern
Michigan showed 8 hour concentrations over the
level of the new health standard.

In central Michigan, Rose Lake (Clinton County)
showed 8 hour concentrations over the new standard,
something not usually observed.

Many sites in SE Michigan were showing high one
hour averages into the evening hours.

Here's the lowdown on smog yesterday  (85 ppb-8 hour
average is the new health standard):

Harbor Beach 116
Otisville  91
Flint 98
Rose Lake (Clinton Co) 96
Tecumseh 90
Ypsilanti 94
Detroit (Linwood) 91
Detroit (7 mile)  88
Allen Park 93
Warren 92
New Haven  89

Today, West Michigan will not likely have problems
because of a cold front coming across the state.

There is no ozone action declaration for SE Michigan,
but review at noon shows winds are only a little bit
higher (still under 9-10 mph)
than they were yesterday and high temperatures
are still occurring there.  The next few hours should
indicate whether any problems are going to occur.
