Elmera Azadpour is a Data Scientist and Data Visualization Specialist for the USGS Water Resources Mission Area.
Elmera received a Master of Environmental Science and Management from the Bren School at the University of California, Santa Barbara. Her masters research examined optimal green infrastructure placements that reduce stormwater runoff pollution in Maunalua Bay, O‘ahu, Hawaiʻi. She received her Bachelor of Science in Environmental Biology from the University of Utah.
Hurricane Isaias made landfall near Destin, Florida as a Category 2 storm on October 9, 2026. Tracking inland through Alabama, its remnants brought damaging winds, heavy rainfall, flash flooding, and life-threatening storm surge from the Gulf Coast to the southern Appalachians and Mid-Atlantic.

This is an animation showing the changing conditions relative to the historic record of USGS streamgages from October 1, 2024 - September 30, 2025. The river conditions shown range from the driest condition seen at a gage (red open circles) to the wettest (blue closed circles). A purple outer ring around a gage indicates it is flooding.
