WS Form E-5


Purpose of the report:

The WS Form E-5 is used to document the hydrologic conditions that were prevalent in each HSA during the month. Specifically, the E-5 details what the monthly river and flood conditions were. An E-5 can be an important asset when it is necessary to document hydrologic events (i.e. surveys, reports, briefings, hydrologic outlooks, etc.).

The report is due:

NO LATER than the 15th of the following month.

For example, if the report is for the month of February, then it should be sent to the appropriate recipients by the 15th of March.

Who is responsible for writing and sending the report?

The preparation of the E-5 is a station function, not just a Hydrologic Program Manager function. If the Hydrologic Program Manager is unavailable to produce and send the report, then another individual in the office must take care of this responsibility.

Who should the report be sent to?

1) Regional HSD - mail, or email to HSD, as appropriate.

2) OH - (Hydrometeorological Information Group) - email address to: HIC

3) The appropriate supporting River Forecast Center(s).

4) If the office is being supported by a SH from another WFO, then the form must be sent to that supporting WFO.

5) Any agencies/entities in which the WFO has an agreement with, to receive this information.

What information needs to be included in the report?

x The box at the top of the WS E-5 form should be checked if the HSA did NOT experience any flooding. Even if no flooding occurred within the HSA, the report should still contain at least a short summary of the predominant hydrometeorological conditions or trends for that month.

o If ANY flooding DID take place within the HSA during the month, leave the box blank and describe the situation in detail.

The rest of the E-5 is basically free form. Aesthetically speaking, there is not a set format that must be followed when preparing an E-5. However, it must contain certain important information - especially if flooding did occur within the HSA that month.

v What to include when NO flooding occurred within the HSA

Even if flooding did not occur, it is still necessary to prepare a short summary of the predominant hydrologic conditions within the HSA that month.

v What to include when flooding DID occur within the HSA

A more comprehensive and descriptive summary is required when flooding did occur. This summary should contain the following information:

w A full description of the flood event(s), the area(s) affected, duration of the event(s), the magnitude, and any other pertinent characteristics of the event(s).

w A brief description of significant hydrometeorological features.

w A full description of damages and deaths, where they occurred, and any available information about the monetary value of the damages.

w A summary of the watches/warnings that were in effect, and any other information relevant to the service that was provided by the WFO during the event.

Ideas on types of information to be included in the report....

1) Overview: Summarize the overall hydrometeorological conditions in the HSA during the month.

If flooding has occurred in the HSA, a more comprehensive and detailed account of the situation will be necessary. In addition to the hydrometeorological information listed above, there should be a descriptive summary of the flood event(s). This should include: the names of the affected river(s); the states, counties, and local areas that were impacted; the date, time, magnitude, and duration of the flood(s); any unique characteristics of the flooding.

2) Temperatures and Precipitation Trends:

What was the overall hydrometeorological situation that month?

Were there any unique hydrometeorological conditions which lead to flooding?

Was there more (or less) precipitation than normal?

Were the temperatures colder (or warmer) than normal in the HSA?

3) River and Basin Conditions

This should be a summary of the river or stream conditions throughout the month. Examples of information could include: Any significant river rises, record low river stages, oil or chemical spills, ice conditions, water supply conditions, drought conditions, dam or levee problems (breaks or breeches), precipitation, and any other useful hydrometeorological information.

4) Hydrologic Products

Did the WFO issue any hydrologic products that month?

If yes, what were they?
