Expected impacts:
- Showers and thunderstorms are
expected from Monday afternoon into Monday night and pre-dawn Tuesday
- Locally heavy rainfall (and
lightning) can be expected at times with some of this activity
- Due to recent heavy rainfall
and saturated ground conditions there will be a higher than normal risk of
low land flooding throughout the period
...Synopsis...
We are closely monitoring a developing weather situation for the period Monday afternoon into Tuesday morning. While some specific details (as to exact rainfall amounts, etc.) are yet to be worked out, it appears probable that locally heavy rainfall can be expected at times across at least some portions of the area during the period, which could lead to flooding of low lying and poor drainage areas at times during the period.
...Forecast...
Showers and thunderstorms are expected to develop on Monday afternoon, initially on a scattered basis. The activity is expected to increase in coverage by Monday evening and continue at times into pre-dawn Tuesday. Locally heavy rainfall (and lightning) can be expected at times with some of this activity. The activity is then expected to decrease in coverage on Tuesday morning.
...Flood Risk...
Due to recent heavy rainfall and saturated ground conditions there will be a higher than normal risk of low land flooding throughout the period in the affected portions of the area, to include probable impacts on low water crossings, etc. Please note that both the Monday afternoon transportation period and the Tuesday morning transportation period would be impacted by this activity, the extent to which will become more clear in later updates.
The reason that the Advisory extends until 12 Noon Tuesday, yet we expect the rain to end pre-dawn Tuesday, is because runoff from earlier rainfall would likely continue well into the morning hours, after the falling rain has ended. If present trends continue, a Flood Watch will likely be required for all or part of the period in later updates.
...A Note About the Remainder of Next Week...
Please also be aware that additional periods of shower and thunderstorm activity appear probable at times from Wednesday through Friday of next week. An elevated low land flood risk is likely to continue throughout the week due to recent heavy rainfall, saturated grounds, and the probability of additional heavy rain at times in at least some portions of the local area. We will issue additional advisories, watches, etc., for specific time periods as the day-to-day situation becomes more clear.
We will continue monitoring the situation and issue updates as conditions warrant.
