Below normal rainfall and above average temperatures continued across central Alabama with several counties added to the Severe Drought (D2) category. Observing sites in the Severe to Extreme Drought category were near 10 inches below normal rainfall for the year. Elmore County 4 NW Ware 11 1448CST 1449CST 0 0 0.00K 0.00K Thunderstorm Wind (58MG) A microburst produced widespread tree and power line damage along Jackson Road. Dozens of trees were uprooted and snapped with at least 10 power poles damaged. A resident in the neighborhood measured 58 knots with a Davis Instrument Wind Sensor. A quasi-stationary cold front was positioned just north of the I-85 corridor. Scattered thunderstorms developed along the front during the afternoon. One of the storms produced a microburst over Elmore County. Note: The measured wind gust of 58 knots is equivalent to 67 mph.

Scattered thunderstorms developed in the afternoon with a couple of trees blown down. Note: The estimated wind gust of 50 knots is equivalent to 58 mph. ALASKA, Northern AKZ225-226 Denali - Northeast Slopes of the Eastern AK Range 11 1044AKS 0100AKS 0 0 0.00K 0.00K High Wind A strong pressure gradient developed in channeled areas of the Alaska range on the 11th of September. A 1030 mb high over the Arctic and a 989 Low over the Bering Sea induced the pressure gradient. A surface trough moved across the range as well. High winds were reported on the 11th at: Zone 225: Peak wind gust of 61 kts (70 mph) reported at the State of Alaska Department of Transportation Mesonet site named Antler Creek. Zone 226: The U.S. Army Mesonet station Edge Creek reported a wind gust to 65 kts (75 mph). 20 0600AKS 21 1155AKS 0 0 0.00K 0.00K High Wind 3 Time Path Path Number of Estimated September 2016 Local/ Length Width Persons Damage Location Date Standard (Miles) (Yards) Killed Injured Property Crops Character of Storm ALASKA, Northern AKZ223-226 Deltana and Tanana - Northeast Slopes of the Eastern AK Range 21 0600AKS 1200AKS 0 0 0.00K 0.00K High Wind A strong pressure gradient developed in channeled areas of the Alaska range on the 21th of September. A 980 Low over the Bering Sea induced the pressure gradient and associated weather front moved across the range as well. At Delta Junction power was lost due to downed power lines by trees snapped by the wind. High winds were reported on the 21th at: zone 223: Peak wind gust of 61 kt (70 mph) reported at OP5 mesonet site at Fort Greely. Zone 225: Peak wind gust of 61 kts (70 mph) reported at the State of Alaska Department of Transportation Mesonet site named Antler Creek. Zone 226: The U.S. Army Mesonet station Edge Creek reported a wind gust to 77 kts (89 mph). ALASKA, Southeast AKZ023 Cape Decision to Salisbury Sound Coastal Area 09 1200AKS 1800AKS 0 0 0.00K 0.00K High Wind A gale force low developed over the central Gulf of Alaska on the morning of September 9th down to 991 MB. This low went inland that afternoon and rapidly weakened. This system caused gale force winds for the outside and inland waters and brief high wind near Sitka during Search and Rescue operations. No damage was reported, but search efforts were hampered. Taiya Inlet 4 NNW Skagway 13 0300AKS 1500AKS 0 0 0.00K 0.00K Flood The atmospheric river moved across the the panhandle from the northeast gulf coast to the southern panhandle Monday through Tuesday morning. There were two bursts of heavy ran with totals near seal level ranging from three quarters of an inch to just over one inch. There was much more rainfall in the headwaters of the Taiya River with rain amounts from one and half to almost three inches at Chilkoot Pass. The initial bout of rain and high freezing levels produced a two and half foot rise on the Taiya River with the river going over minor flood stage of sixteen point five feet. The river remained just under moderate flood stage through the early morning hours of September 13th from the persistent rainfall. There was another burst of heavy rainfall and the river rose another half foot to go over the moderate flood stage of seventeen feet and crested at seventeen point twenty seven feet around 9 am. The rain tapered off through the late morning and the Taiya River began to slowly recede to be below minor flood stage by Tuesday afternoon. The National Park Service reported that there was significant flooding along the Chilkoot trail with waist deep water at the lower portions of the trail. An atmospheric river that extended deep into the north Pacific moved over Southeast Alaska on September 12th and 13th. This plume of sub-topical moisture slowly moved through the area Monday afternoon through Tuesday morning with expected rainfall amounts over the northern Lynn Canal region of 1 to 3 inches. Also as the front spread east across the region it increased the freezing levels to be above the ridge tops of six thousand feet. This allowed for increased runoff from snow and ice melt in the Taiya River basin. The combination of the runoff from the snow/ice melt and the heavy rainfall produced moderate flooding along the Chilkoot trail by Tuesday morning. ALASKA, Southern AKZ101 Anchorage Muni to Bird Creek 11 1840AKS 2215AKS 0 0 0.00K High Wind A 994mb low pressure system crossed the Alaska Peninsula and moved into Bristol Bay. The associated warm front brought high winds to Anchorage as it crossed the Kenai Peninsula. 4 Time Path Path Number of Estimated September 2016 Local/ Length Width Persons Damage Location Date Standard (Miles) (Yards) Killed Injured Property Crops Character of Storm ALASKA, Southern Wrn P.w.

The Resurrection River, adjacent to the Seward airport, rose 5 ft in 24 hours, resulting in water and debris impacting the runway and causing a 2 day closure of the airport.
