View Of Hurricanes - Continued Dry Here

Edited to add: Visible image of Maria at 2045 UTC this afternoon as she heads toward Virgin Islands and Puerto Rico at Cat. 5 intensity.


Although low-level moisture has inched upward here in southeastern Arizona, considerably more is needed to develop CAPE at low elevations. September has produced only 0.12" rainfall so far, and looks like this month may be turn out to be driest ever since my records started in 1999.


Visible satellite images from 1315 UTC this morning of Cat. 5 hurricane Maria above and Cat. 1 hurricane Jose below. Puerto Rico may be more seriously impacted by Maria than it was by Irma.


Below is from 00 UTC run of the WRF-GFS at Atmo and shows model forecasted precipitation, on 5.4 km grid, out through 5:00 pm MST on September 26th. Pretty grim for Arizona, while New Mexico has very wet conditions east of the Continental Divide.
