south of Cape Fear, NC with sustained

Tropical Storm Beryl made landfall near
Jacksonville Beach, FL with near-
hurricane winds of 115 kph (70 mph).
A rain-maker, Beryl, dumped 10-20 cm
(4-8 inches) of rain; a welcome relief for
the drought-stricken region.
Beryl weakened quickly
15. BERYL: A RAINMAKER
Beryl became a rainmaker as it
weakened and moved
northward along the USA’s east
coast, complicating the
Memorial Day holiday traffic.
