El Niño Is Likely to Develop This 2023, According to PAGASA (SPOT.ph)

El Niño Watch has been raised by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA)- Climate Monitoring and Prediction ...

It is the warm phase of the El Niño-Southern Oscillation (ENSO) cycle, a recurring large-scale climate pattern across the Equatorial Pacific Ocean. It can also cause tropical cyclones to become erratic, pushing tropical cyclones northward with the possibility of stronger intensities, according to PAGASA. It will issue an El Niño Alert if the probability of its occurrence rises to 70% or more, and an El Niño Advisory once it develops. It will bring warmer temperatures, fewer clouds, and below-normal rainfall, the dry season will be extended and rainy season will be delayed, and fewer tropical cyclones in the Philippines. So what are the effects of El Niño? (SPOT.ph) Feeling the heat?

Better model consensus on El Nino, but not its intensity or impact (The Hindu BusinessLine)

Most models have concluded that the prolonged La Nina has ended, and the East Equatorial Pacific is transitioning into a “neutral” state before giving in later ...

Rainfall: Above normal over most of country except Jammu & Kashmir, Himachal Pradesh, Punjab, Ladakh, coastal Karnataka, Goa, Madhya Maharashtra and west Madhya Pradesh. June: Below normal for most of country except Jammu & Kashmir, Himachal Pradesh, and Punjab where it will be above normal. May: Above normal for most of country including South. September: Mostly below normal for entire country. Rain deficit likely to be predominant over coastal Karnataka and Kerala. Temperature: April-May-June: Rajasthan, Gujarat, west Madhya Pradesh, west Maharashtra, coastal Karnataka, Kerala and south Tamil Nadu are likely to observe warmer than normal conditions. Rain deficit over central Madhya Pradesh, east Uttar Pradesh, Bihar, Jharkhand, West Bengal and coastal Karnataka. Overall, rains will likely stay above normal over the South and the hills of North-West India; below normal over North-East India; and near-normal over the rest of the country. Similarly, a trough will combine with a cyclonic circulation over the East and the South to bring isolated to scattered rain and thunderstorm over the region. An India Meteorological Department (IMD) outlook for March 23-29 has already indicated western disturbance activity and an induced cyclonic circulation will trigger isolated to scattered rain and thunderstorms over the hills of North-West India and adjoining plains during many days of the week. Most models indicate prevailing thunderstorms would continue and cool down most of the country during April as well. What is interesting could be the build-up during April and May, normally when the heat begins to build up over North-West India, adjoining Central India and even East India.

'Be ready': What Australians can expect for summer after El Niño ... (9News)

All eyes are on the sky as La Niña finally ends, but two experts have warned even more catastrophic conditi...

[[email protected]](mailto:[email protected]). "We've had three years of good rain, which means good growth. "We'll be doing our best to try and catch up as much as we can but realistically we're not going to be able to catch up before next summer. "We will prioritise the work we can, but we're just not going to get it all done." "That's what firefighters do everything to try and prevent. "The memory for me is when we started to lose lives, and then firefighter lives as well," he said. "Now we have grass everywhere and it's not just a little, it's a lot, and the water table is quite high, so it will keep growing. "The concern is there is also climate change happening in the background, so if we do have an El Niño it's going to be hotter and drier than what it would have been," she said. Adding to the concern is the fact the service is "way behind" on mitigation strategies like burn-offs because of the persistent wet weather. "Leading into that 2019/2020 fire season we were on the back of a multi-year drought, so there was no grass in the west at all," he told 9news.com.au. "It doesn't matter if we have El Niño, summer means bushfire risk for Australia and we need to get ready," Dr Jaci Brown said. But the research director for CSIRO's Climate Intelligence Program said Australians need to "be ready" for a bad bushfire season - regardless of whether El Niño develops or not.

Angat water enough for dry season (The Manila Times)

THE National Water Resources Board (NWRB) on Wednesday gave assurances that the Angat Dam, which supplies 96 percent of Metro Manila's water needs, ...

David said preparations for the El Niño were underway, including the construction of the Putatan and Cardona water treatment plants, as well as deep wells in strategic locations. The El Niño phenomenon is characterized by the abnormal warming of sea surface temperature in the central and eastern equatorial Pacific Ocean, as well as below-normal rainfall. said in a radio interview, noting that the dam's water level is higher than the normal level of 192 meters.

PAGASA issues El Niño Watch; public urged to conserve water (Philstar.com)

MANILA, Philippines — State meteorologists on Thursday issued an El Niño Watch, indicating the increased likelihood that the weather phenomenon ...

But if cyclones approach the country, their winds and rains are likely to be more intense. In 2019, Metro Manila and neighboring provinces experienced water shortage as the El Niño contributed to a massive decline in rainfall. “We have a window for anticipation.

El Niño may persist until 2024: PAGASA (ABS-CBN News)

El Nino, a weather phenomenon characterized by below-normal rainfall that can lead to dry spells and drought, may persist until 2024, PAGASA said.

Let us wait for the update of our forecast, then we can update the projections. Ang tinitingnan natin na magkakaroon tayo ng challenges sa water supply is next year," he said. El Niño is the warm phase of the naturally-occurring climate pattern El Niño-Southern Oscillation (ENSO), marked by changes in wind direction and sea surface temperatures in the equatorial Pacific. The forecast prompted the weather agency to issue an El Niño Watch, which is released when "conditions are favorable" for the development of El Niño in the next 6 months and the probability is 55 percent or above. (It's just monitoring and preparatory activities so in the coming days the impact of El Niño will not be seen yet.) Climate projections by PAGASA show that El Niño will begin by the third quarter of 2023 or between July and September, and will last until next year.

PAGASA warned that El Niño increases the likelihood of below-normal rainfall conditions, which could bring dry spells and droughts in some areas of the country.

NBC2 viewer question: What causes the flip from La Niña to El Niño? (NBC2 News)

In simple terms, La Niña refers to the occasion when cooler than average water is observed in the Pacific Ocean along the equator off the coast of South America ...

This is called El Niño, when warmer than average water becomes commonplace along the equatorial Pacific. It didn’t form until August of the 1992 hurricane season, but that year was during an El Niño event when there were forces working against hurricanes in the Atlantic. This is called La Niña, when cooler than average water becomes commonplace along the equatorial Pacific. Despite the trend toward El Niño this hurricane season, we must still be well prepared for whatever the weather may throw our direction. Everyone in our community is well aware of how last hurricane season played out, so it’s probably no surprise to hear that it was a La Niña year. On the other hand, El Niño refers to the period of time when those same waters run warmer than average.
