Southwest Climate Outlook September 2016 - Climate Summary
Climate Summary from the September issue of the CLIMAS Southwest Climate Outlook
Precipitation & Temperature: August precipitation totals were above average across most of Arizona and New Mexico (Fig. 1a), buoyed by a surge of monsoon storms that started in late July and extended through the first week of August, and a surge of moisture linked to Tropical Storm Javier in mid-August. August temperatures were mostly average to below average in Arizona and New Mexico (Fig. 1b), a decline that did not alter the overall seasonal pattern of very warm temperatures observed during the summer months (Fig. 2). September precipitation to date (Sept 1 – Sept 14) ranges from well above average in southeastern Arizona and portions of New Mexico, tied mostly to heavy rains during Hurricane Newton, to well below average in other areas of the region that did not record as much activity during this time (Fig. 3). Water year precipitation to date (Oct 1, 2015 – present) is below average in much of the Southwest, particularly in Southern California, most of southern Arizona, and western New Mexico (Fig. 4).
