Narrative:

On jul/mon/06; at approximately XA00-XB00 local time; denver international airport stopped accepting arrival aircraft due to windshear alerts and thunderstorms. Several aircraft were forced to hold at skeed intersection. Additionally; the southeast arrival route was impassable due to WX. These aircraft were rerouted to the southwest arrival route; with the understanding that 15 mit would be provided. It was not. What other factors contributed to this lack of spacing are unknown by me at this time but a couple of possibilities are: 1) lack of vision or direction by the traffic management unit; and 2) lack of initiative on the part of supervisors at the first level. Without me giving my best effort; this situation could have been extremely unsafe.
