(an Alternate Airport, following an approach and missed approach at the destination, if the destination requires an alternate.)
Pretty clear to me, if wx at destination drops below alternate requirements inflight, you need to either ensure you have an alternate following missed approach at destination or re-plan to new destination at the point when advised of wx below alternate requirements. If this is not available a decision would be made to proceed to the safest airport option and file the subsequent incident report.
Interesting what Shot Nancy mentions about there companies inflight fuel policy. Shot what is the wording used in the (Minimum Inflight Fuel Requirements) of your company manual?
