A shop ceiling collapsed while the building was being battered by a storm following a heat wave in Thailand.

The electronic gadgets shop was closed for the day after authorities issued a severe weather warning in Chonburi province, Thailand on April 25.

But strong gusts swept the area while repairmen worked for the day before the structure gave in about an hour later.

CCTV footage shows the ceiling crumbling down on cabinets, shelves, tables and chairs where the iPhones, Android smartphones, and assorted accessories were kept.

Before the structure was destroyed, workers were seen outside the shop salvaging parked motorcycles. The wind blew away a huge water container, with one of the men falling onto the two-wheelers.

The strong winds blowing appeared to have weakened the foundation of the already damaged steel ceiling, which caused it to fall.

Shop owner Wirakan Kan Worasinsakun said: ‘I am relieved that no one was hurt because there were no customers that day and the phones were not damaged. The repairmen also left after the strong winds hit our shop.'

The storm came as temperatures soared to 45 degrees Celsius last week during a heat wave across the Asia Pacific region.

Maximiliano Herrera, a climatologist and weather historian, described the scorching heat as the 'worst April heatwave in Asian history'.

In Thai capital Bangkok, residents were warned not to go outside amid 42 degrees Celsius temperatures causing power outages due to surging demand from air con units and fans running.

The country's national weather service said the heat index - what the temperature feels like when combined with humidity - hit a record 54C (129F).

The warm weather is now giving way to extreme tropical storms.

The Thai Meteorological Department warned that southerly and southeasterly winds prevailing over upper Thailand would strengthen between April 23 and 26.

Outbreaks of summer storms, accompanied by thunderstorms, gusty winds, hail, and lightning strikes, were expected to affect the northeastern and eastern parts of the country first, before spreading to other regions.
