Hurricane Newton moved into Baja California as a Category 1 hurricane packing winds near 80 mph and gusts near 100 mph.
It is showing some signs of weakening over the next 12 hours as it moves over the Gulf of California and then makes a second landfall over Northwest Mexico tonight as a tropical storm.
It will likely remain a tropical storm as it moves into southern Arizona early Wednesday.
As it approaches, we're getting a surge in moisture today and Wednesday.
Flash Flood Watches have been issued in anticipation of this moisture and the increasing storm chances.
The best potential for widespread, flooding rainfall looks to be in Southeast Arizona where we could see 1 to 3 inches of rainfall.
While the rain threat looks lower for the Phoenix metro, there is a chance we could get scattered storms Tuesday night and through the day on Wednesday. Any storms that develop will have the potential of producing very heavy, flooding rain.
Tropical moisture will linger through the end of the week, keeping at least a slight chance of Valley storms each day through Friday.
