...HIGH POLLUTION ADVISORY FOR MARICOPA COUNTY INCLUDING THE GREATER
PHOENIX AREA FRIDAY...

The Arizona Department of Environmental Quality in Phoenix has issued
an Ozone High Pollution Advisory for the Greater Phoenix Area for
Friday.

This means that forecast weather conditions combined with existing
ozone levels are expected to result in local maximum 8-hour ozone
concentrations that pose a health risk. Adverse health effects
increase as air quality deteriorates.

Ozone is an air contaminant which can cause breathing difficulties
for children as well as persons with respiratory problems. A decrease
in physical activity is recommended.

If it is a regularly scheduled work day, you are urged to car pool,
telecommute or use mass transit.

The use of gasoline-powered equipment should be reduced or done late
in the day.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Fri Sep 4 2020

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

The National Hurricane Center is issuing advisories on Tropical
Depression Omar, located about 475 miles east-northeast of Bermuda.

1. A nearly stationary and poorly-defined area of low pressure is
located over the east-central tropical Atlantic about midway
between the west coast of Africa and the Windward Islands. This
system continues to produce disorganized showers and thunderstorms,
and some slow development could occur during the next couple of
days before it merges or interacts with the large tropical wave
currently located just west of the Cabo Verde Islands.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...30 percent.

2. A tropical wave and area of low pressure located just west of the
Cabo Verde Islands is producing a large area of disorganized
showers and thunderstorms. Gradual development of this system is
expected as it moves westward to west-northwestward, and a tropical
depression is likely to form late this weekend or early next week
when the system reaches the central tropical Atlantic.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...high...80 percent.

3. Another tropical wave is forecast to move off the west coast of
Africa on Sunday. Gradual development of this system is then
expected, and a tropical depression could form by the middle of
next week while it moves generally westward over the far eastern
tropical Atlantic.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...60 percent.
