| Episode narrativeepisode_narrative | Hurricane Sally initially formed as an area of disturbed weather over the Bahamas late on September 10th, 2020. Over the next few days, the system became better organized and became Tropical Depression Nineteen in the afternoon hours on September 11th. Later that night around midnight CDT on September 12th, TD Nineteen made landfall at Key Biscayne with peak winds of 35 mph and a central pressure of 1007mb (29.74 inHg). The system continued west emerging into the east-central Gulf of Mexico and quickly strengthened into a Tropical Storm later in the day on the 11th. This system continued to drift northwestward with time and strengthened into a hurricane in the morning hours on September 14th with maximum sustained winds of 85 mph and a central pressure of 985 mb (29.09 inHg) and continued to strengthen becoming a category 2 hurricane shortly after. Sally would then eventually weaken some, and slow down in forward speed before turning very slowly northwards making landfall near Gulf Shores, Alabama as a strong Category 2 hurricane with peak winds of 105 mph and a central pressure of 965mb (28.50 inHg) early in the morning hours on September 16th.||Impacts to southeastern Louisiana and southern Mississippi was mostly confined to coastal counties of southern Mississippi, southeastern Louisiana and adjacent marine areas. Main impacts included storm surge inundation for coastal areas, as well as some wind damage across portions of Jackson and Harrison County, MS while Hurricane Sally was making landfall east across Gulf Shores, AL. Rainfall was of little impact across coastal MS and westward with only small areas of rainfall totaling around 3 inches reported in eastern Jackson county. |
