Tropical Cyclone Hellen, which intensified very rapidly and is close to the equivalent of a Category 5 hurricane, is bearing down on Madagascar.

From the RMSC Tropical Cyclone Center in La Reunion:

HELLEN IS LIKELY TO BE ONE OF THE MOST POWERFUL TROPICAL CYCLONE EVER SEEN OVER THE NORTHERN CHANNEL SINCE THE SATELLITE ERA (1967).

GIVEN THE PAST TRACK OVER THE LAST 6 HOURS MORE SOUTH-EASTERN THAN PREVIOUSLY EXPECTED, THE LIKELIHOOD IS INCREASING FOR AN EXTREMELY DANGEROUS TROPICAL CYCLONE LANDFALL OVER THE NORTHWESTERN COASTLINE OF MADAGASCAR BETWEEN CAPE SAINT-ANDRE AND MAHAJONGA.

GIVEN THIS POSSIBILITY, THE RSMC TROPICAL CYCLONE STORM SURGE NWP HAS BEEN RUN THAT SHOWS PHENOMENAL SEA ELEVATIONS IN THE AREA EXPOSED TO THE NORTHERLY WINDS (EAST OF THE FORECAST TRACK). THIS POTENTIALLY STRENGTHEN AREA IS VERY SENSITIVE BECAUSE ITS BATHYMETRY (PLATEAU)AND STORM SURGE COULD REACH BETWEEN 2M AND 4M IN THE ESTUARY OF THE BETSIBOKA RIVER (MAHAJONGA), MORE THAN 7M IN THEBAY OF BALY (SOALALA) AND BETWEEN 1M AND 4M ON THE COASTLINE EAST OF CAPE SAINT-ANDRE.

ALL PREPARATIONS FOR A "WORST CASE" SCENARIO SHOULD BE UNDERWAY
