Tropical Depression Dando Flooded Mozambique

NASA's Terra satellite captured a look at Tropical Depression Dando as it was making landfall on January 16 in Mozambique. Dando's light to moderate rains caused flooding and displaced residents of the capital city of Maputo. Dando has since dissipated.

NASA's Terra satellite passed over Dando on January 16, 2012 at 07:50 UTC (2:50 a.m. EST). The Moderate Resolution Imaging Spectroradiometer (MODIS) Instrument aboard Terra captured a visible image of the storm, and showed that it had good circulation with an identifiable center of circulation. The bulk of clouds and rainfall associated with Dando at that time was within its southern quadrant, as the clouds appeared thicker and whiter on satellite imagery.

According to the Associated Press, almost 500 people were displaced from their homes in Maputo from the flooding generated from Tropical Depression Dando. Dando made landfall on January 16, 2012 bringing light to moderate rainfall and gusty winds. The rainfall may not have been heavy but it was enough to cause the closure of low-lying bridges and roads. All Africa.com reported on January 18 that areas of Mozambique are flooded.

Gusty winds from Dando caused damage to schools and homes in the Inhambane and Gaza provinces. Fortunately, there were no human deaths associated with the storm, however, AllAfrica.com reports as many as 1,000 goats perished in the Gaza province. Agricultural damages were also reported there.

REMARKS:
210900Z POSITION NEAR 18.0S 37.8E.
TROPICAL CYCLONE (TC) 08S, LOCATED APPROXIMATELY 555 NM NORTH-
NORTHEAST OF MAPUTO, MOZAMBIQUE, HAS TRACKED NORTHWESTWARD AT 01
KNOT OVER THE PAST 06 HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY INDICATES THAT TC 08S HAS UNDERGONE RAPID INTENSIFICATION
OVER THE PAST SIX HOURS AND NOW HAS A WELL DEFINED 8 NM DIAMETER
EYE. DESPITE ITS PROXIMITY TO THE AFRICAN CONTINENT (APPROXIMATELY
25 NM), LAND INTERACTION IS HAVING MINIMAL IMPACT. ADDITIONALLY, AS
TC 08S TRACKS SOUTHEASTWARD BACK OVER THE OPEN WATERS OF THE
MOZAMBIQUE CHANNEL, IT IS EXPECTED TO FURTHER INTENSIFY SLIGHTLY,
PEAKING AT 115 KNOTS. A 210501Z SSMIS 91GHZ IMAGE DEPICTS TIGHTLY-
CURVED BANDING AND VIGOROUS EYEWALL CONVECTION. THE CURRENT
INTENSITY IS BASED ON AGENCY DVORAK ESTIMATES OF 102 KNOTS. TC 08S
IS EMBEDDED WITHIN A WEAK, YET COMPLEX STEERING ENVIRONMENT AND HAS
BEEN QUASI-STATIONARY AS IT IS CONSTRAINED BY SUBTROPICAL RIDGES
(STR) POSITIONED TO THE EAST AND POLEWARD. THE RECENT 500MB ANALYSIS
CONTINUES TO SHOW A WEAK TROUGH MOVING EASTWARD OVER SOUTH AFRICA.
AS THE STR TO THE SOUTH WEAKENS WITH THE APPROACH OF THE UPPER-LEVEL
TROUGH, TC 08S IS FORECAST TO SLOWLY TRACK SOUTHEASTWARD UNDER THE
STEERING INFLUENCE OF THE EASTERN STR, WHICH IS EXPECTED TO BUILD
OVER MADAGASCAR AFTER TAU 24 NOW THAT TC 07S (ETHEL) HAS BEGUN TO RE-
CURVE AWAY FROM THE REGION. THE UPPER-LEVEL TROUGH IS FORECAST TO
RAPIDLY PROPAGATE EASTWARD, AND IS NOT EXPECTED TO DEEPEN ENOUGH TO
PROVIDE A RE-CURVE MECHANISM FOR TC 08S. FOLLOWING THE TROUGH
PASSAGE, THE STR SHOULD RE-BUILD SOUTH OF THE SYSTEM IN THE EXTENDED
TAUS. IN TURN, THIS SHOULD PROVIDE A WESTWARD STEERING INFLUENCE
BACK TOWARD MOZAMBIQUE, HOWEVER THE TRACK IS EXPECTED TO REMAIN SLOW
IN THIS WEAK ENVIRONMENT WITH SEVERAL COMPETING FACTORS. DESPITE THE
FORECAST COMPLEXITY, NUMERICAL MODEL GUIDANCE IS IN FAIR AGREEMENT
WITH THIS SCENARIO, HOWEVER THE NOGAPS AND GFS MODELS SUGGEST
ANOTHER STRONGER TROUGH MAY START TO MOVE THROUGH AT THE END OF THE
FORECAST PERIOD AND PREVENT TC 08S FROM MAKING LANDFALL. THIS
FORECAST IS IN-LINE WITH THE MODEL CONSENSUS. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 210600Z IS 21 FEET. NEXT WARNINGS AT 212100Z AND
220900Z. REFER TO TROPICAL CYCLONE 07S (ETHEL) WARNINGS (WTXS31 PGTW)
FOR TWELVE-HOURLY UPDATES.
