Post-tropical cyclone Olga hit our area last night fast and furious. For a storm that developed into a tropical depression on Friday morning, she moved ashore quickly, bringing rain and wind overnight, mostly during the early morning hours.
Houma areas received an estimated 6 inches of rain within a 24-hour timespan, at least, with some receiving up to 8 inches, according to Tim Destri, senior forecaster of National Weather Service New Orleans. Some areas southwest of Houma received an estimated 10 inches of rain within that timespan, Destri said.
The Thibodaux area received less amounts of rainfall, with the storm bringing in an estimated 4.02 inches of rain in Thibodaux and an estimated 6.1 inches of rain 8 miles north of the city for the duration of the storm, Destri said.
Terrebonne and Lafourche Parishes were under Flash Flood Warnings from around 11 last night through 5:45 a.m. In Houma, roadways were flooded as rain came down quickly. By mid-morning, the majority of the floodwaters receded quickly.
When Olga was off the Louisiana coast, the storm’s winds were around 50 mph, but when she moved inland over the Terrebonne and Lafourche Parish areas, winds were reported at 30-40 mph, Destri said.
As of 11 a.m., Entergy is reporting 2,579 customers still without power in Terrebonne Parish and 412 without power in Lafourche.
