DeGRIB NDFD Weather Shape File Fields - MDL
Degrib: Wx-inten shapefile field
In the following table keep in mind:
-
If there was "No Weather", I didn't care what intensity it was.
-
The "gray background" weather types were added on 1/20/2004.
-
Hail was supposedly removed on 8/12/2004, but I left its place in the table.
-
With version 1.60 (8/24/2004), I introduced "Unknown Intensity" values. The reason I introduced them was that the weather string seems to change over time. I wanted to be able to encode that I didn't recognize the intensity. Prior to that, the table did not have the "Unknown Intensity" values, so "BD" used to start with 6 instead of 7.

Degrib: Hazard shapefile field
There are 5 hazards per word, and prior to Aug 2004, there was 9 types of hazards, so each hazard was given a digit (see table below). The digits were sorted, and the result was stored in the Hazard field for a given word. Example: "SmA,DmgW" became "54000", which after it was sorted became "00045", which was stored.
After Aug 2004, there were 12 types of hazards so we needed 2 digits per hazard. Our previous example would be "0504000000" which would then be stored as "0000000405".
In the following table keep in mind:
-
The "blue font" hazard types were added on 8/13/2004.
-
OR, MX, Mention, Primary are not hazards, so I chose to map them to "None".
-
The current method is limited to 25 hazards. The code can be modified to handle more, but currently it is limited to 25.
