Extreme precipitation events across the Northwest, although rare, impact the region by causing increased runoff, flooding, damages to infrastructure and loss of life and property. These impacts may be enhanced if an extreme event is synchronous across a basin or region as opposed to being a localized occurrence. Understanding the degree to which precipitation extremes are spatially synchronized provides additional insight into their potential impacts and the atmospheric processes that promote spatially coherent precipitation extremes. Using data from the National Weather Service Cooperative (COOP) and the Natural Resources Conservation Service Snow Telemetry (SNOTEL) stations, 3-day precipitation accumulations exceeding the 95th percentile are examined over the past two decades. Simple metrics are used to show the relationship between distance and the probability of synchronous occurrence of extremes between station pairs, the regional representativeness of each station, and the preferential direction for coherence. Additionally, the relationship between Pineapple Express events and coherent extremes is examined. Initial results show that the spatial coherence of extremes between stations decays with distance, and that there are spatial patterns to both measures of regional representativeness and preferential direction of coherence. The role of Pineapple Express events in producing extreme precipitation exhibits clear spatial patterns across the region, and though many of the most coherent extreme events have coincided with these storms, Pineapple Express storms do result in regional extreme events of both high and low coherence.
