What is the River
Watch Program?
It is a voluntary program in which we are asking pilots and village residents to
report observations of river ice conditions. Pilots are asked for reports on what they see along their normal route
of flight and at their standard flight level.
What is an example of
a river condition that you would like to have reported?
We are focusing on reports of river ice during the
breakup process, but would welcome ice reports during other seasons as well.
Who are the pilots
that help out?
We had a great response from the air taxi operators in Alaska. These pilots are
flying between rural communities on a daily basis, and are in a great position
to notice change on the river. We have
gotten reports from State and Federal agency pilots during their normal course
of operations. We also have a small
group of general aviation pilots who have been interested enough to volunteer
to fly out to check on specific areas where we need some information about
conditions.
How would a pilot
submit a report?
The primary format for submitting a report is as a remark on
a standard pilot report or PIREP. Most of the time, these are passed by the
pilot to the FAA Flight Service Stations over the radio. A web based form can also be used.
Reports can also be emailed to the National
Weather Service in text or digital photo formats. Telephone reports can also be given.
Are the FAA Flight
Service Stations aware of this program?
The FAA Flight Service Stations are quite supportive of this
program. The NWS has given training presentations to FSS staff to assist the
implementation.
How would a village resident
submit a report?
A web-based form can be filled out or reports can be emailed to the National
Weather Service in text or digital photo formats. Telephone reports can also be given.
What kind of training
is needed for submitting a report?
It helps if observers understand a little bit about the process
of river ice break-up. In our training we have a hydrologist explain the mechanics
of ice break-up and provide common terminology for key stages of the ice breakup
process. We have a good collection of photographs which illustrate these stages.
Observers can attend a training session or go through the presentation on
the program web site. We have also developed a checklist of terms and an
observer guide book.
How will the
information be used?
The National Weather Service is responsible for monitoring
the ice breakup process to identify the potential for flooding due to ice jams. Alaskan
rivers are also heavily used for transportation and knowledge of the status of
the breakup process is useful for knowing when it is safe to use boats. Reports
from observers can significantly increase the information available for these
purposes.
How do the observers get
feedback on the use of their reports?
The observer reports appear on the program web site along with
reports from other sources. We also summarize the information on a map
illustrating the status of ice breakup on major rivers in Alaska. This map has been displayed on the
Alaska Weather Program for many years during the ice breakup process.
When does the ice
break up in Alaska?
Most of the breakup activity occurs during May, but some
locations begin in April and the North Slope completes
the breakup process in early June.
