While the extreme heat will briefly fade across northwestern India this week, dangerously hot temperatures will remain elsewhere across the country.
Thursday marked the hottest April day for New Delhi since 2010.
"Temperatures soared to 43.2 C (109.8 F) at Safdarjung Airport and 44.9 C (112.8 F) at the Indira Gandhi International Airport on Thursday," AccuWeather Senior Meteorologist Kristina Pydynowski said.
"Safdarjung, which is located closer to downtown New Delhi, has not recorded a temperature that high since the middle of April 2010," she said.
The extreme heat has prompted officials in Telangana to commence summer vacations early for all schools starting on Friday, according to the Times of India. Schools will also be closed in Tamil Nadu.
Temperature in Telangana claimed 40 more lives in the State.
The highest death toll recorded is in Karimnagar District alone, while Khamam and Nagarkurnool recorded 4 death's each and Bhadari recorded 3 deaths. Ranga Reddy District, Mabubnagar, Manche-rial and Kamareddy recorded 2 deaths each district while single death each district is recorded in Sangareddy, Medchal, Warangal (Urban and Rural), Mahbuba-bad, Siricilla, Suryapet, Wanaparthy.
The report submitted by the The State Disaster Management Authority (SDMA) to the government states the high temperature all over the State.
Three-member committee is formed including a local mandal revenue officer, sub-inspector of police, and a medical officer in mandal by the District Collectors to enquire about the death of victims due to heatwave.

Winter has returned to most of Europe and the chill has reached as far south as Turkey and Greece.
The Jet Stream is pulling cold air from the Arctic causing much of Europe to endure much colder than normal temperatures for the time of the year
It’s so cold in the night in Switzerland farmers have introduced frost protection with fire buckets in the vineyards of Switzerland during the night to protect the vines against frost.
Rare April snow downs trees, creates travel chaos in eastern EuropeAreas from Romania to Moldova and Ukraine were the latest in Europe to receive rare and disruptive April snow this week.

|Big Space Weather! Magnetic storms: A massive returning Coronal Hole: Active sunspot area AR2644 returns and a dark filament of magnetism explodes! |

Solar wind is flowing from this massive coronal hole and has reached Earth early causing magnetic storms around the Earths magnetosphere: Credit: NASA/SDO.
This is a "coronal hole" (CH) -- a vast region where the sun's magnetic field opens up and allows solar wind to escape.
Gaseous material (solar wind) flowing from this coronal hole reached Earth at remarkable speeds of almost 800 km/s and is causing geomagnetic storms, see below
We've seen this coronal hole before.
On March 27th it lashed Earth's magnetic field with a fast-moving stream that ignited intense auroras around both of Earth's poles.
The coronal hole is potent because it is spewing solar wind threaded with "negative polarity" magnetic fields.
Such fields do a good job connecting to Earth's magnetosphere and energizing geomagnetic storms, see below.
The K-index, and by extension the Planetary K-index, are used to characterize the magnitude of geomagnetic storms.
Kp is an excellent indicator of disturbances in the Earth's magnetic field and is used by SWPC to decide whether geomagnetic alerts and warnings need to be issued for users who are affected by these disturbances.
The principal users affected by geomagnetic storms are the electrical power grid, spacecraft operations, users of radio signals that reflect off of or pass through the ionosphere, and observers of the aurora.
The massive Coronal hole is not the only returning visitor causing disturbances in the Earth's magnetic field
Old sunspot AR2644 has returned--and it is still active.
In early April the active region produced a series of M-class solar flares and shortwave radio blackouts.
Now, following a two week trip around the farside of the sun, AR2644 is has returned.
On April 18th at approximately 2000 UT, the sunspot's magnetic canopy exploded and hurled a bright coronal mass ejection (CME) into space.
Note: By longstanding tradition, sunspots that travel around the backside of the sun and re-appear are renumbered. AR2644 therefore has a new designation: AR2651 see below.
Earlier this morning around 0500 UT, a dark filament of magnetism on the sun exploded. See the movie below from NASA's Solar Dynamics Observatory.
An analysis is underway to determine if any portion of the debris is heading for Earth. Stay tuned.
|About 1,276 tonnes of dead fish affecting 75,000 fisherman following last month's flash floods in Bangladesh: Rice to compensate fisherman! |

About 1,276 tonnes of fish died in Haor areas of four districts following last month's flash flood caused by incessant rain, a government report says.
In total, over 74,500 fishermen were affected due to the deaths of fish, the report obtained by The Daily Star.
Of the total, 25 tonnes of fish died in Moulvibazar, 49.75 tonnes in Sunamganj, 1180.85 tonnes in Netrakona and 21 tonnes in Sylhet.
No information on deaths of fish was available from Habiganj, Brahmanbaria and Kishoreganj, the report said.
And of the total affected fishermen, 4,000 are from Moulvibazar, 44,445 in Sunamganj, 16,528 in Netrakona and 9,653 in Sylhet.
The report also proposed for distributing 20 kilogrammes of rice to each affected fishermen for the duration of a month.
For this, it estimated that 1492.48 tonnes of rice will be needed.
Fish in some of the parts of the haor areas have died due to a fall of pH and oxygen levels and a rise of ammonia in the waters, the report said based on information from the districts.
The pH level fell to 5 from 6.5 and oxygen .02ppm from 3.0-4.0ppm during the flash flooding.
Level of ammonia rose to 1.00ppm from the usual level of .02ppm, the report added.
Six vigilance teams were formed in Moulvibazar, Sunamganj, Sylhet, Hobiganj, Brahmanbaria, Kishoreganj and Netrakona districts.
The teams are visiting the haor areas and testing quality of water.
A team led by a joint secretary of the ministry has been engaged in inspecting activities on the field levels.
