Showers lingering in the wake of an initial front which moved through the panhandle on Monday will give way to an atmospheric river pushing into the southern panhandle by Tuesday afternoon that will result in moderate to heavy precipitation. This moderate strength atmospheric river is expected to have IVT values reaching upwards of 750 kg/ms and will have its strongest impacts in the southeast panhandle around Ketchikan and Annette Island. This is expected to bring rainfall totals between 2.5 and 3.5 inches to the southern panhandle between Tuesday afternoon and Wednesday afternoon. The rest of the central and northern panhandle will still see some moderate to heavy rain, and is expected to see between 1.5 and 2.5 inches between Tuesday night and Wednesday night. Heaviest rain rates during this event will be between 0.10 and 0.15 inches per hour extending from the southern panhandle up through Skagway. The heavy rain will last a longer duration in the southern panhandle, but a shorter duration is expected when it impacts the northern panhandle. Flooding is not currently expected with this heavy rainfall, however river rises will occur. For the latest information, visit www.weather.gov/Juneau.
