Rosa rapidly strengthens into a major hurricane, threatens Mexico

Rosa has rapidly intensified into a major hurricane on September 27 far away from the coast of Mexico.

There are currently no coastal watches or warnings in effect but Rosa is expected to turn toward Baja California and make landfall early next week as a tropical storm.

Rosa: Widespread moderate to locally heavy rainfall, southwestern U.S.

While Hurricane Rosa is expected to weaken to a tropical storm by early next week, its moisture should stream into the southwestern U.S. bringing widespread moderate to locally heavy rainfall. This should particularly focus over the state of Arizona where areal averages may reach 1 to 2 inches with pockets of higher amounts. On average, Phoenix typically sees a little over 0.50" of rainfall in October.

Here is the latest rainfall forecast from NWS' medium range desk. Note: the graphic is forecast totals for Days 1-7, but the first few days will be dry.

More big hailstones

Percentages of large hailstones are among the highest seen since the turn of this century, according to preliminary SPC reports.

In the United States, very large hail reports for 2018 stretch from Idaho to Florida to Connecticut, with a maximum in the western Great Plains.
