Frequently Asked Questions
-
How can I
get old river stage values?
- How can I get
weather information for a certain date?
- Why don't you
forecast for river X or city Y?
- A number of factors come into
play when deciding which rivers and towns receive forecasts:
-
Size matters - All
River Forecast Center forecasting operations are geared
towards larger streams and rivers...points that do no see
significant rises until at least 6 hours after rainfall
begins. In the MARFC area, this generally translates into a
stream draining at least 50 square miles.
-
Location, location,
location - In general, there should be a river gage
where we make our forecasts. We need stage readings to help
us set up our forecasting procedures for that point and to
tell us how well our models are handling the situation.
-
The powers that be -
In the end, it is a combination of local emergency
management officials and the National Weather Service who
decide which locations are forecasted.
-
Do you have
information/photographs from the Hurricane Agnes/January 1996/March

best bet is to check with your local library or historical
society first
