2 hurricanes making their way through Pacific Ocean: What to know about potential impacts to Hawaii, West Coast

Key Points:

• Hawaii is experiencing high surf impacts this weekend due to Hurricane Lowell and Tropical Storm Karina, with advisories in effect for waves up to 12 feet on south and southeast shores and rough surf on east-facing shores.
• Hurricane Lowell, a Category 4 storm with 145 mph winds, is expected to pass west of the main Hawaiian Islands by Tuesday, bringing heavy rain, gusty winds, and potential flash flooding, especially on Kauai and the Big Island.
• Tropical Storm Karina, weakening and located over 750 miles from the Big Island, will likely dissipate by Sunday night but continues to generate high surf on Hawaii's east-facing shores.
• Hurricane Marie, located about 700 miles from Baja California, is weakening but causing rough surf and dangerous rip currents along the southern California coast, with a "high risk" of life-threatening rip currents through Labor Day.
• The active tropical activity in the central and eastern Pacific is influenced by El Nino, contributing to multiple storms affecting coastal regions without making landfall.
