- Landfall is not expected, but the storm's proximity is already drawing deep tropical moisture into Arizona.

- FOX 10 Phoenix and ABC15 are both tracking the storm's moisture contribution to the monsoon pattern.
Tropical Storm Marie, currently off the coast of Mexico and expected to stay out to sea, is pulling deep tropical moisture into Arizona and raising Phoenix rain chances to 30 to 40 percent between Thursday night and Saturday morning, according to Arizona's Family meteorologist April Warnecke.
Landfall is not expected. The storm is tracking northwest and remaining offshore, but its proximity is enough to funnel moisture northward. Heavy rain is possible across the state over the next several days, with the position of a ridge of high pressure determining which areas see the most activity. A slight chance of showers continues into late Saturday through Monday.
FOX 10 Phoenix is also tracking the storm's moisture contribution, noting that monsoon rainfall totals are already split across the state heading into the weekend. ABC15 reported a possible boost in monsoon moisture toward the end of the week tied to the newly formed storm.
Temperatures will hover slightly below the seasonal norm at 100 to 103 degrees through Sunday. The Valley opened Wednesday at a high of 103 under mostly clear skies, near normal for early September. Labor Day is forecast at about 105.
Rain chances will be updated through the weekend as the storm's track becomes clearer.
