#cawx /JzaWihbf2k- NWS San Diego SeptemHeavy desert rainfall expected as Kay proceeds The greatest potential for heavy rainfall and flash flooding is for the east slopes of the mountains and adjacent deserts areas for Friday afternoon and night. Updated rainfall potential through Sunday from the moisture from tropical cyclone Kay. Rainfall amounts of 6 to 10 inches are possible throughout Baja California, with localized totals of 15 inches on the peninsula and up to 6 inches on the far west Mexico mainland, bringing the risk of flash floods and mudslides in mountainous areas. Precipitable water values (the amount of water vapor in a vertical column above a given point) are in the 2-to-2.5-inch range over a large area surrounding Kay. This moisture will be funneled up the Gulf of California as Kay continues moving north-northwest. The hurricane is embedded in a very moist air mass, with mid-level relative humidity around 70%. Kay’s most distinctive feature is its expansive plume of moisture.

Given Kay’s angle of approach and its unusually large wind field, there could be significant storm surge along the coast near and east of Kay’s track. 2,300), which sits on a natural south-facing harbor. This sparsely populated area is home to Mexico’s largest wildlife refuge, the El Vizcaíno Biosphere Reserve. On this track, Kay is predicted to move over or near the sharp westward jut of mid-Baja on Thursday evening, most likely as a borderline category 1 hurricane/tropical storm. Kay’s north-northwest motion of 15 mph is roughly parallel to the Baja Peninsula.
However, Kay will remain a large, sprawling storm capable of widespread impacts. Kay had moved over cool 23 degree-Celsius (73☏) waters associated with the cold southward-flowing California Current, so a gradual weakening of the top winds is expected.
Heavy rains from Kay were soaking Mexico’s Baja Peninsula, and an outer spiral band from the hurricane had moved into Southern California, bringing rain to the San Diego and Los Angeles areas. EDT Thursday, Kay was a category 1 storm about 60 miles southwest of the coast of Mexico’s Baja California Peninsula, with top sustained winds of 85 mph.
