Until The Monsoon Cometh

Nevada's Southwest deserts
are mostly arid dry
until the Monsoon cometh early in July.
Sudden torrential downpours
are very rarely seen
until the Monsoon cometh as a "raining" queen.
Inundation by flash floods
are seldom in a surge
until the Monsoon cometh as a "petty scourge."
Vertical mountain cascades
are devoid of a trace
until the Monsoon cometh as a "master race."
Humidifying moistures
are dissonant displays
until the Monsoon cometh as "water ballets."
Nevada's Southwest deserts
are mostly sand and dust
until the Monsoon cometh ending in August.
