| Bright sunshine beneath the heat dome will
contribute to an increase in ozone today.
Because the El Niņo contributed to a protracted drought in the
Caribbean basin, very late episodes of Saharan dust and Mesoamerican smoke
also bring fine particulate matter into the lower part of the moderate
category. An increase in monsoon
activity will enhance scattered showers in the Panhandle, but elsewhere, hot,
dry weather with only isolated showers enhances high fire danger through the
period. Any fires may produce locally
unhealthy smoke. It the southerly
breezes diminish early next week, then ozone in urban areas and in the very
dry western counties may increase near or beyond the top of the moderate
category. |
