If the destination is tempoing (= change of up to one hour) thunderstorms then perhaps carry an extra one hours holding. If, in addition, the alternate is also tempoing the same then best find another alternate with better weather!
Flying around in such weather without a lot of extra fuel puts crews under enormous pressure and, I believe, this accident is an example of what can happen. The crew and, in particular, the captain have all my sympathies and it was fortuitous that all initially came away more or less unscathed.
I have yet to read the full transcipt of the accident report but I feel that operating close to minimum fuel reserves was a major factor in this accident and in the circumstances the crew were fortunate in carrying out a "controlled" arrival at an airport rather than running out of fuel downwind.
