Heat Wave in Malaysia...Maybe the worst yet...
The heatwave caused by El Nino.


In Malaysia, there were relatively stronger El Nino events in 1972, 1982, 1991 and 1997, with 1997 being the strongest year. Perhaps 2016 will rival or surpass that.

Malaysia’s daily mean temperature is between 26°C to 28°C, and at the lowlands temperatures are between 22.5°C at night and 33°C in the daytime, according to the biennial update report (BUR) that Malaysia submitted to the UN Climate Change Convention recently.

On March 19, The Star reported that temperatures had jumped to 39°C in Kangar, 38°C in Alor Setar, 36°C in Penang and Ipoh, and 35°C in Johor Baru, Kota Baru and Kuala Lumpur.

Compare this with the normal average daytime mean temperature of 33°C. Imagine if this kind of heatwave temperature were to be permanent.

The following are among the effects of El Nino in Malaysia:

> Unbearably hot conditions in homes and work places without adequate air conditioning, resulting in health problems such as headaches, fever and even a few deaths.

> Among the most affected are infants and children, the elderly and those who are sick. Schools in some states were forced to close for some days when temperatures exceeded the unhealthy level.

> A decline or absence of rainfall, causing a drop in water levels in reservoirs, parched agricultural lands and delays in planting of rice. Water shortages may soon emerge.

> Decline in agricultural production. According to Malaysian Agricultural Research and Development (Mardi), a two-degree temperature rise could lead to a 13% reduction in padi yield. A 15% decline in seasonal rainfall could lead to a drop in yield of up to 80%.

> The rise in sea temperature has resulted in fish migrating, affecting fish catch, according to the Agriculture and Agro-based Industry Ministry.

> The heatwave results in more fires on agricultural land, forest and peatlands. Besides the damage caused, this also contributes to “haze”.

> Reduced water flow may increase the concentration of pollutants such as ammonia, organic and solid matter in streams and rivers. This may threaten marine life and the safety of water used for human consumption.

> There is greater intensity of energy use due to increased use of air conditioners to counter the heat. This makes it more difficult to control Greenhouse Gas emissions.

@Sudhir: Morbe Dam which supplies water to Navi Mumbai is fully owned by NMMC so it's details are not available publicly .. Please refer this link hopefully some information may be helpful to you.. Also local newspapers might be covering storage details so see supplements of Navi Mumbai special in Lokmat, Sakaal, Loksatta, Mata Marathi dailies... http://m.timesofindia.com/city/navi-mumbai/NMMC-plans-water-cut-schedule-to-ensure-supply-till-July-end/articleshow/51500337.cms

Navi Mumbai gets water supply from The Morbe Dam. (Small amount is supplied to Kharghar and Kamothe).
The dam level at Morbe has reached 70m on March 28, with the gross storage being recorded at 53.66 million cubic meters (MCM). Morbe dam has storage capacity of 190 MCM. About 28% full.
Water cannot be released to the treatment plant if the level goes below 55m, which is termed as dead storage.

The civic administration has already brought down the quantity of water supplied in phases from 421 MLD since mid-September to the current 300 MLD.
The civic body will be able to provide 300 MLD of water only for the next 129 days.

For the dam to overflow, 3500mm of rainfall is required. For water supply to last through the year 3,000mm of rainfall is necessary,'" said an official.
