I have just one question concerning the Local weather API Response Fields (I haven’t found an answer neither in the documentation nor in the forum):

prob_precip_pct: What does the return value “<1” mean? A probability of precipitation falling less than 1%?

Yes that’s exactly right, it means a less than 1% probability of precipitation falling.

I was also wondering about this. I have retrieved a forecast in json and XML format. One day in particular has a timeframe with a description of “Torrential rain shower” (code 82), and a couple of other timeframes with indications of fairly heavy rain. The result indicates the forecasted amount of precip_mm as anywhere around 11.0 to about 16.0. Yet, in every case, the prob_precip_pct never changes from “<1” for each timeframe throughout the entire day. In this case, all 7 days retrieved showed “<1” for the prob_precip_pct in every timeframe object (even though precip amounts were indicated), and each parent object (Days[x]), showed prob_precip_pct as 0.

Am I missing something here? If an amount is given as the forecasted amount of precipitation, wouldn’t the chance of precipitation would be greater than 0? A “Torrential Rain Shower” day should certainly be more than 1% probability, I would think.

Please advise…

BUMP – I would also like to have an answer to Eric’s question above. Thanks!
