Water vapor is typically scarce, and using indoor air to drive the hydration reaction can reduce the building's humidity to an uncomfortable level while the cold outside air contains limited moisture.

Desert beetles and lizards, for example, have evolved to develop surface structures that have both hydrophilic and hydrophobic areas and effectively capture moisture from the air.

Similar atmospheric river events - when small regions of moisture travel outside tropical regions - have occurred throughout North America over the last few weeks.

The low pressure system off the Pacific Northwest coast driving this storm will begin rapidly intensifying Tuesday — reaching the threshold of a bomb cyclone — which will drastically increase its moisture and strength.
