On Sunday afternoon, Tropical Depression 15 formed in the eastern Pacific. It was a large and relatively organized system, but once it got going, it got going. It began to intensify Sunday afternoon, becoming Tropical Storm Newton by Sunday evening.

This storm is fascinating as it made it all the way to the US-Mexico border in Arizona as a Tropical Storm. It was initially forecasted to make it into southern Arizona as a tropical cyclone, but it was just declared to be post tropical by the National Hurricane Center.

Despite this, Newton is still bringing the threat of heavy rainfall and flash flooding to southeastern Arizona and western New Mexico as the center of Newton moves to the north and east. The WPC highlighted this in their outlook for flash flooding today, issuing a slight risk for flash flooding in that region this afternoon.
Heavy rainfall totals have already been noted closest to the border of Mexico and the US in southeastern Arizona. Totals up to 5″ have been noted there. Currently, however, Newton is weakening. This is continuing to produce weaker precipitation as His remnants move inland.

Nevertheless, the remnants of Newton will continue to make their way to the northeast, and will likely to produce heavy rainfall and isolated flash flooding along its path.
