Formatted Wind Direction returning N/A instead of a number

[Gerard Cerchio]

This morning we had a very unusual occurrence here at Ocean Beach San Francisco. The wind speed dropped to 0 mph for a short period. This resulted in the value of $currentwindDir.formatted being set to N/A upsetting my wind gauge javascript which expects a numerical value.

Do I need to add some code to check the $currentwindDir.formatted  is numerical or is there a more reliably numerical weewx value I may use to set my wind direction gauge?

Thanks.

See the section There is no wind direction when wind speed is zero in the User's Guide.

Thanks Tom, That'll fix it!

Zero wind at Ocean Beach? It's definitely going to be a hot one today in Contra Costa County. (NWS says 104F today and 112 tomorrow)
