Details:
* WHAT...Flooding caused by excessive and long duration rainfall.
* WHERE...All of northern and central Arizona.
* WHEN...From Sunday evening through Tuesday evening.
* IMPACTS...Flooding will be possible over burn areas, low-water
crossings, creeks, streams, washes and swimming holes. Larger
creeks and rivers may exceed bankfull. Flooding of paved roads and
highway underpasses will be possible. Unpaved roads could become
muddy and impassable.
* ADDITIONAL DETAILS...
- Low pressure will interact with tropical moisture from the
eastern Pacific. This could potentially produce numerous showers
and embedded thunderstorms, with heavy rain that will fall over
saturated soils and burn scars. This could lead to localized
flash flooding and rises on local rivers, such as the Little
Colorado River.
- Additional information is available at weather.gov/flagstaff.
Information:
You should monitor later forecasts and be alert for possible Flood
Warnings. Those living in areas prone to flooding should be prepared
to take action should flooding develop. |

BAROMETRIC PRESSURE
The air that makes up our atmosphere exerts a pressure
on the surface of the earth. This pressure is known as atmospheric pressure. It is measured in inches/Hg. Generally, the more air above an area, the higher the atmospheric pressure. Barometric pressure changes with local weather conditions, making barometric pressure an important and useful weather forecasting tool. High pressure zones are generally associated with fair weather, while low pressure zones are generally associated with poor weather.
For forecasting purposes, the absolute barometric pressure value is generally less important than the change in barometric pressure. In general, rising pressure indicates improving weather conditions, while falling pressure indicates deteriorating weather conditions.
