Although the level of moisture flowing through the sky doesn’t have a one-to-one relationship with rainfall amounts, having more moisture can boost the odds for rainfall extremes, if there’s a force to squeeze that moisture out, such as the cluster of thunderstorms that hit the #GrandCanyon. This weekend, there was an additional force at play. Moisture from the remnants of #TropicalStorm #Iselle was flowing across the West, siphoned inland by a #HeatDome & further waterlogging the atmosphere.

These forces drove the deadly #GrandCanyon #FlashFlood The #Arizona #monsoon is only one part of a bigger #weather story. This weekend’s #FlashFlooding, which has killed at least one person in the Grand Canyon, wasn’t an isolated weather event. The torrential rain was part of Arizona’s monsoon season, which runs from June 15 through Sept 30. But the monsoon alone doesn’t tell the whole story. #ClimateChange #ExtremeWeather

A record-breaking #ElNiño & a #marine #heatwave in the #Pacific Ocean have combined to load the atmosphere with moisture, helping fuel the deadly #flooding. On the backdrop of #ClimateChange, these factors have driven atmospheric moisture levels 5 to 15% higher than average. That has loaded the dice for downpours this summer, such as those that hit the #GrandCanyon Saturday. #ClimateChange #ExtremeWeather #FlashFlood #monsoon #weather
