DISCUSSION AND OUTLOOK ---------------------- At 1100 AM HST (2100 UTC), the eye of Hurricane Lowell was located near latitude 15.2 North, longitude 163.7 West. Lowell is moving toward the north near 6 mph (9 km/h). A northward to north-northeastward motion at a faster forward speed is expected through Tuesday. On the forecast track, the center of Lowell will move across portions of the Papahanaumokuakea Marine National Monument, just west of the main Hawaiian Islands, Monday night. Lowell is forecast to turn toward the northwest and slow down by early Wednesday after passing the Hawaiian Islands. Data from an Air Force Reserve Hurricane Hunter aircraft indicate that maximum sustained winds are near 120 mph (195 km/h) with higher gusts. Lowell is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Little change in strength is expected through today, but gradual weakening is forecast to begin tonight. Lowell is expected to remain a hurricane while passing near Hawaii. Hurricane-force winds extend outward up to 50 miles (85 km) from the center and tropical-storm-force winds extend outward up to 175 miles (280 km). The minimum central pressure based on dropsonde data is 948 mb (28.00 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Lowell can be found in the Tropical Cyclone Discussion under AWIPS header HFOTCDCP4 and WMO header WTPA44 PHFO. WIND: Tropical storm conditions are expected in Kauai County by Monday afternoon or evening. Wind speeds atop and on the windward and leeward sides of hills and mountains are often up to 30 percent stronger than the near-surface winds, and wind gusts to hurricane force are possible. Hurricane conditions are expected in the Papahanaumokuakea Marine National Monument between Nihoa and French Frigate Shoals Monday night, with tropical storm conditions beginning Monday afternoon. RAINFALL: Lowell is expected to produce rainfall totals of 6 to 10 inches for Kauai, with maximum totals of 14 inches possible. For the Big Island, 4 to 8 inches of rain is expected with isolated totals of 12 inches possible. For Maui, 2 to 4 inches of rain is expected, with isolated maximum totals of 8 inches possible. Across the remaining islands, rainfall of 2 to 4 inches is possible. This rainfall may produce significant flash flooding and mudslides, especially across Kauai County and portions of the Big Island. For a complete depiction of forecast rainfall associated with Hurricane Lowell, please see the National Weather Service Storm Total Rainfall Graphic available at hurricanes.gov/graphics_ep12.shtml?rainqpf STORM SURGE: The combination of storm surge and tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... Kauai County...1-3 ft Oahu...Up to 1 ft The deepest water will occur along the immediate coast near and to the right of the center, where the surge will be accompanied by large and destructive waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. For a complete depiction of areas at risk of storm surge inundation, please see the National Weather Service Peak Storm Surge Graphic, available at hurricanes.gov/graphics_cp4.shtml?peakSurge. TORNADOES: Several tornadoes are possible near Kauai and Niihau Monday afternoon through Monday night. A few tornadoes are also possible across the remainder of the Hawaiian Islands. SURF: Swells from Lowell are likely to cause life-threatening surf and rip current conditions during the next several days across many of the Hawaiian islands. Please consult products from your local weather office. NEXT ADVISORY ------------- Next intermediate advisory at 200 PM HST. Next complete advisory at 500 PM HST.
