Hurricane Florence Made Landfall Friday Sep 14,2018
Florence made landfall on Friday Sep 14,2018, with the centre of the storm
striking Wrightsville Beach in North Carolina, with gales of up to 90mph
(150 km/h).
The National Hurricane Center says that despite the gradual lowering
in wind strength, the storm remains extremely dangerous because of the
high volume of rainfall and storm surges predicted.
Georgia, North and South Carolina, Virginia and Maryland have
declared a state of emergency as forecasts showed Florence dumping
historic amounts of rain on the area.
Florence originated from a strong tropical wave
that emerged off the west coast of Africa on August 30. Steady
organization resulted in the formation of a tropical depression on the
next day near Cape Verde.
Progressing along a steady west-northwest trajectory, the system
acquired tropical storm strength on September 1, and fluctuated in
strength for several days over open ocean. An unexpected bout of rapid intensification ensued on September 4–5, culminating with Florence becoming a Category 4 major hurricane on the Saffir–Simpson scale with estimated maximum sustained winds
of 130 mph (215 km/h). Thereafter, environmental conditions tore the
storm apart, and Florence degraded to a tropical storm by September 7.
Shifting steering currents led to a westward turn into a more suitable
environment; the system regained hurricane strength on September 9 and
major hurricane status by the following day. At 16:00 UTC
on September 10, Florence again became a Category 4 hurricane, later
reaching a new peak intensity with winds of 140 mph (220 km/h) and a
central pressure of 939 mbar (27.7 inHg). Afterwards, Florence weakened
slightly as it underwent an eyewall replacement cycle,
but began to restrengthen late on September 11. However, early on
September 13, the storm weakened to a Category 2 hurricane, due to
exposure to moderate wind shear, but the storm's wind field expanded
during this time. On the evening of September 13 it was downgraded to
Category 1. Early the next day on September 14, Florence made landfall
just south of Wrightsville Beach, North Carolina.
