The Upcoming Rainy Season

Four months after the Tsunami most of the survivors of the Tsunami remain in temporary shelter - in tents or accommodated by family and friends, despite the massive fundraising by the governmental and non-governmental organizations. The affected remain vulnerable to a variety of environmental stresses as the seasons marches on.

On the whole, the period since the Tsunami has been just slightly wetter in Sri Lanka than normal in most parts of the island. January to March is a relatively dry period and it is only now as April ends that the Yala rainfall is expected. Thus the shelters, the drainage, the septic systems and drainage systems shall be exposed to heavy rainfall.

<>The conditions are right for mosquito breeding and this is one season of heightened malaria transmission unless drains are cleared and other mitigatory steps are taken. The roofing in temporary and other shelters shall be exposed to rain. If the tsunami related debris has not been properly disposed and the munipal waste disposal is improper, then rain can leach contaminants into the ground water. If the drainage systems blocked up the tsunami debris and damage has not been cleared this is the time when water logging can lead to myriad other problems. In these and myriad other ways, the coming rainfall can lead to conditions that can impair the particularly vulnerable. Proper attention is needed as Yala approaches. See Figures
