Procedure; Weather; Human Factors
The Captain advised me he was diverting to ABQ; with FOB (fuel onboard) of 7.0. I advised ABQ burn of 4;296 LBS with reserve of 3;652 LBS; and suggested LAS as being less burn since I observed he was using reserve fuel to divert to ABQ. I made sure he declared minimum fuel with ZAB. I also repeatedly queried his current FOB and fuel over destination to verify I was calculating fuel correctly.Erroneous ATC communication about TUS closure; irregular operations with dust storm at PHX. My desk had 4 PHX arrivals at the same time during a dust storm; this was not an optimum workload.Aircraft attempted to land PHX with 2 SM visibility; Captain at that point felt weather conditions were unsafe; asked to divert to listed alternate of TUS. ATC advised TUS was closed; which was incorrect. Captain advised he was diverting to ABQ. I feel the cause of this low fuel arrival was communications. I was unaware of the fact that ATC had advised the Captain that TUS was closed. There were a few scattered cells in TUS area; which was why I thought he chose ABQ instead.
Air carrier Dispatcher reported high work load and ATC confusion about airport conditions contributed to a less than optimum diversion plan.
