Travellers are advised to watch out for signs of methanol poisoning such as blurry vision and confusion, which can lead to serious illness and death. Methanol is an industrial chemical found in antifreeze and windscreen washer fluid. It is not meant for human consumption and is highly toxic. But there have been instances of unscrupulous backyard brewers adding methanol to drinks to make them go further, and some bars and street sellers mixing it with spirit-based drinks and cocktails to cut costs.
Authorities have warned residents to avoid unnecessary travel as waters inundate transportation infrastructure. Flood warnings were issued due to heavy rain causing travel chaos and fatalities.
