SUBJECT: Soliciting Comments until June 17, 2016 on

         Proposed Changes to the Excessive Rainfall Outlook

 

The NWS National Centers for Environmental Prediction's (NCEP)

Weather Prediction Center (WPC) is accepting comments until June

17, 2016, on its proposal to change the Excessive Rainfall

Outlook as follows:

 

- replace "SEE TEXT" with a 2 percent "Marginal" contour.

 

- provide the new 2 percent Marginal contour on the Day 1, Day 2,

and Day 3 products (currently "SEE TEXT" is only provided on Day

1).

 

- allow issuance of a "high risk" on Day 2 (currently restricted

to Day 1).

 

- color-fill the graphical web product.

 

A comparison of the current product and proposed product is

available at: http://www.wpc.ncep.noaa.gov/qpf/newero/

 

These changes provide more specific risk information farther out

in time and align the look of the product with other national

center outlooks.

 

Products affected by this proposed change include the web

graphics (http://www.wpc.ncep.noaa.gov/qpf/excess_rain.shtml) as

well as the following:
