Two storms -- Hurricane Kiko and Tropical Storm Lorena -- are developing in the Pacific Ocean and may cause flash flooding, rip currents and high surf conditions in the United States.
Tropical Storm Lorena, which is forecast to move into northwestern Mexico in the coming days, was a hurricane and has since weakened. It could bring flash flooding to the Southwest on Friday and Saturday as remnants of the cyclone may cause heavy rain in the area. This heavy rainfall could hit Arizona through Friday, according to the National Weather Service (NWS).
Flood watches are in effect for portions of California and Arizona on Thursday, including Phoenix and Tucson, with 1 to 2 inches of rain per hour hitting these areas.
Lorena could also cause life-threatening surf and rip current conditions that may hit "portions of the southern and western coasts of Baja California Sur during the next couple of days," the NWS said. The Baja California Peninsula could could see up to 8 inches of rain due to Lorena.

While Kiko will be moving into cooler waters and a less conducive atmosphere over the weekend, which could weaken the storm, the state of Hawaii could still face impacts from the storm.
Either as a weak hurricane or tropical storm, Kiko will be near Hawaii next Tuesday and Wednesday and the island could expect dangerously high surf and strong wind gusts up to 70 mph on Tuesday through Thursday.
Depending on the location of Kiko, flooding rains are also possible, especially in higher terrain.
These two hurricanes come after Hurricane Erin lashed North Carolina's Outer Banks with rough waves and coastal flooding last month.
While these two hurricanes are forming in the Pacific Ocean, the National Hurricane Center predicted an above-normal hurricane season for the Atlantic.
