In the present day an enormous low middle extends over a lot of the northeast Pacific, whereas a powerful plume of moisture–an atmospheric river– stretches southwest-northeast in the direction of the California coast.

Wish to be impressed much more? Right here is the water-vapor satellite tv for pc picture on the similar time, viewing the emission of water vapor to house. Scary for northern California!
For reference, right here is the sea-level strain evaluation on the similar time, with low-level temperatures and winds additionally proven. Maybe the most important low-pressure middle I can keep in mind spreading over an unlimited space. With heat air from the southwest on the southern facet (orange colours). That’s the atmospheric river.
To actually hit that residence, beneath is a map for a similar time (this morning) of a potent diagnostic of atmospheric rivers, built-in vapor transport, IVT. This describes how a lot water vapor is being pushed round by the wind.
Blue colours present very excessive values within the core of the atmospheric river.
Substantial precipitation will fall immediately and tomorrow in California and Oregon from this atmospheric river (see forecast beneath). Northern California has been probably the most anomalously dry a part of the Golden State. Now not.
