A heat index phrase will be generated whenever the calculated heat index exceeds or equals the
|
|
<B>"Heat Index"</B> threshold.<BR><BR><BR><BR><BR>

|
The wind chill threshold is more complex, since three threshold criteria need to be met
|
|
for a broadcast of the wind chill index value:<BR>
|
|
* The temperature must be at or below the <B>"Max Temp"</B> value.<BR>
|
|
* The wind speed must be at or above the <B>"Min WS"</B> value. Do not choose a value less than 5
|
|
mph, since the wind chill equation does not permit values below this threshold.<BR>
|
|
* The calculated wind chill index must be at or below the <B>"WCI"</B> field.
