at landfall, a trough was accelerating nora northwards, causing it to reach a forward speed of 30 mph (50 km/h). late on september 25 (utc), still a tropical storm, it entered the continental united states at the california-arizona state line. nora began to weaken rapidly, and was downgraded to a tropical depression three hours later, while located between blythe and needles, california. nora reached arizona while still tropical, becoming the third known system to do so. nora degenerated over land, and the low-level center moved towards the north-northeast. a remnant circulation aloft persisted, however, and was likely responsible for a period of near hurricane-force winds observed at the nws cedar city, utah doppler weather radar. the remnants gradually became more diffuse over the following two days while moving generally northeastward, through portions of utah, colorado, idaho and wyoming.
