An area of low pressure above Sri Lanka has caused heavy rainfall across the country since 14 May 2016. Some locations saw over 350 mm (13.77 inches) of rain fall in 24 hours. Floods and landslides have caused havoc in as many as 19 districts of the country, including around Colombo.

Strong winds, lightning and falling trees have also caused major damage.
Sri Lanka’s Disaster Management Centre (DMC) report said that since 13 May, over 200,000 people have been affected, with 134,000 currently displaced and staying in 176 relief camps set up for the victims. Almost 1,300 homes have been damaged and 68 destroyed.

“Showers or thunder showers will occur at times in the Northern, North-central, North-Western, Western, Central and Sabaragamuwa provinces and in the Galle and Matara districts.
“Heavy falls (more than 100 mm) are likely at some places.

Lightning Strikes Kill 60 in Bangladesh Thunderstorms
Severe weather is also affecting countries further north. The European Commission’s Humanitarian Aid and Civil Protection department (ECHO) reported yesterday that a staggering 60 people have been killed as a result of lightning strike in Bangladesh over the last few days, with experts blaming increased deforestation in Bangladesh. ECHO say:
“A week long heatwave in Bangladesh with average temperatures well above 30 degrees, culminated the last two days in thunderstorms across the country. The storms, locally known as Nor’westers or the Kalbaishakhi, came with heavy lightning which left more than 60 people dead, most in the rural parts of the country.
“Experts say that this highly unusual number of fatalities is due to the increased deforestation in Bangladesh. If the number of deaths continues to escalate, as more thunderstorms are predicted, Bangladesh could be moving towards calling the event a natural disaster”.
Voice of America also reported that deforestation had played a role. VoA said:
“Gawher Nayeem Wahr, member-secretary of the Bangladesh Disaster Preparedness Forum, said the decreasing number of tall trees has a role in the increase in number of people being injured or killed by lightning strikes.
“Palm and other taller trees usually attract the lightning flashes. But with these trees becoming scarce in rural areas” people are more prone to be hit, Wahr said.”
