Tropical Storm Henri (2003)

The eighth storm of the season, Henri was one of six tropical cyclones to hit the United States in the year.

On September 1 the wave axis entered the Gulf of Mexico, and upon doing so convection steadily organized around a low-level center of circulation.

The system moved northward and developed into Tropical Depression Twelve on September 3 while located about 300 miles (480 kilometers) west of Tampa, Florida.

Embedded within a slow mid-latitude trough, the depression moved eastward and strengthened into Tropical Storm Henri on September 5.

[1] Despite strong southwesterly vertical shear, Henri continued intensifying while moving eastward, and reached a peak strength of 60 mph (97 km/h) later on September 5.

Henri was not able to recover its intensity, and made landfall near Clearwater, Florida on September 6 as a 35 mph (56 km/h) tropical depression, and quickly crossed the state as it accelerated to the northeast.

[1] Despite initial predictions of re-intensification over open waters due to potentially lower shear,[2] Henri failed to re-strengthen and degenerated into a remnant low pressure area on September 8 off the coast of North Carolina.

[1] The broad and disorganized remnant low remained nearly stationary due to a ridge of high pressure to its north.

[1] Residual convection within the remnants of Henri remained disorganized, but forecasters kept watch for the potential for redevelopment.

[1] Flood warnings were issued across the state prior to the storm making landfall, with predictions of 5 to 10 inches (127 to 254 millimetres) of rainfall.

[11] A feeder band in Charlotte County dropped 7 in (180 mm) of rain in three hours, flooding numerous streets and homes.

However, lightning from a feeder band injured a man in Lee County, while an indirect injury occurred from a car crash due to hydroplaning.

[15] In North Carolina, Virginia, and Maryland, rainfall was generally light, with the exception of a few areas receiving over 3 inches (76 mm).

[citation needed] On September 23, just days after the storm moved through, President George W. Bush declared New Castle County, Delaware as a disaster area following the effects of Henri and later Hurricane Isabel.

[25] Over twenty volunteer organizations met to establish a long-term committee to find resources for disaster recovery needs.
