MANILA, Philippines?Make sure your electric fans and air conditioners are working, for hotter days are yet to come.
The temperature could peak at a scorching 38 degrees Celsius in Metro Manila and up to 40 degrees in northern Luzon, particularly in Cagayan province, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
This is due to the persisting ridge of high pressure across Luzon, which ushers in fair weather, PAGASA weather specialist Nonoy About said Sunday in a phone interview.
Residents of parts of Manila will bear the brunt of the summer heat on Tuesday because of a 12-hour water interruption.
Maynilad Water Services Inc. is cutting off the water supply to Paco, Pandacan, Ermita and Malate to pave the way for the rehabilitation of a pumping station in Ermita.
The water interruption will last from noon to midnight Tuesday.
PAGASA's About warned the public to exercise "extreme caution" when the temperature soars to between 32 and 41 degrees. He said this was enough to cause sun stroke, heat cramps and heat exhaustion.
The temperature reached 34.8 degrees-the highest so far this year?at 1:45 p.m. Sunday at the Quezon City Science Garden, one of the three monitoring stations in the metropolis.
In Cabanatuan, Nueva Ecija, and Tuguegarao, Cagayan, the temperature rose to 36 degrees.
"Summer has just started so we can expect warmer days ahead," About said.
This is not so good news for farmers in northern and central Luzon, who would have to bear the blistering heat while harvesting their crop.
About said the temperature in those areas could soar to a scalding 38 to 40 degrees, especially in the month of May when the weather usually becomes more intense.
Mindanao, however, will have a respite from the scorching heat due to the easterly waves in the Pacific Ocean. The waves would usher in light to moderate rains in the region in the next few days.
The hottest day ever recorded in Manila by the Port Area monitoring station was on May 17, 1915, when the mercury climbed to 38.6 degrees.
On May 14, 1987, the hottest temperature of 38.5 degrees was recorded at the Quezon City Science Garden.
Tuguegarao sizzled when the temperature rose to 42.2 degrees on May 11, 1969.
Jesus Matubis, Maynilad assistant vice president for corporate affairs and media relations, said only certain streets of Manila "will experience temporary water interruption, not entire districts."
Water will be cut off in Paco and Pandacan, bounded by Quirino Avenue, PNR Street, Creek Street and Pedro Gil Street; and Ermita and Malate, bounded by Creek and Apacible streets, UN Avenue, Taft Avenue, M. Kalaw Street, Roxas Boulevard and Quirino Avenue.
The Pandacan area, bounded by Pedro Gil Street, Quirino Avenue and Creek Street, will experience low pressure to no water.
Maynilad advised residents to store water for their needs during the cutoff. The water concessionaire won't be deploying water tankers to those areas because the cutoff will be temporary, Matubis said.
"They should store water before the interruption," he said. "This is just one of the regular maintenance works."
For clarification, residents may call the Maynilad hotline 1626, or 436-2000, or text Maynilad 2898, Matubis said.
