Chitchat NEA Weather Forecast For Feb 2017

What did we get yesterday?
SINGAPORE - Flash floods were reported in various parts of Singapore including the Orchard Road area as heavy rains hit the island on Wednesday (Feb 8) evening.
Singapore's water agency PUB said on its Twitter page at about 6pm that there were flash floods at Orchard Boulevard towards Paterson Road, and at the junction of Hill Street and Stamford Road.

weather forecast is not an exact science, especially in sg where the island is so tiny in a region of turbulent and unpredictable weather conditions. just where i am all weather forecasts from 4 major news networks predict a break in wet weather today but the opposite is true. it rains cats, dogs and rats. and all 4 major networks have the latest and greatest meteorological equipment and software including doppler radars strategically stationed in several spots in an area larger than the whole of the malay peninsula. you must thank your lucky stars for getting precipitation.
On the contrary, being a tiny peesai is easier to forecast. with modern equipment, trends, records and satellites, forecasting weather in tiny SG is a piece of cake. The only reason NEA got it so wrong is incompetence
on the contrary it's easier to predict rain or no rain in a larger geographical area. for example, rain cells in shower conditions are dispersed in pockets of rain here and there, making it difficult for meteorological forecasters to pinpoint exactly where and when rain cells will directly pass over a district let alone an entire city. in doubt they would broadcast on tv that rain may occur somewhere in the area but can't be 69% sure. the language used is "chance of rain" or "passing showers" across the north bay with "possible sprinkles" in the south bay. sg is smaller than santa clara county and thus will face spotty passing rain cells as big as pulau tekong. very hard to pinpoint rain in siglap, showers in bedok, and nothing in changi. how to be precise like that? :p
on the contrary, the meteorologist can see the formation of storm cells and their movements. NEA's record is complacency and incompetence. I have been monitoring their forecasts and it goes generally like this:
Generally sunny with isolated showers in some parts of Singapore. Temperature range is between 24 to 32 degrees. Relative humidity is 85%
Hello, in equatorial Sg such forecast is 95% safe. And this lure NEA into complacency and they recycle that forecast day in and day out. It is a freak thunderstorm like yesterday's that showed their complacency.
But they will tell ignorant people that it is difficult to predict weather. It is because it is difficult to predict that we need meteorologists. But what's the point if they always get it wrong when we need it most?

don't be goondu lah. meteorologists use computer models to predict movement of atmospheric moisture based on pressure gage readings, temperature sensor readings, weather radar sweeps, but cannot be 96% certain about how they will develop over a 69-hour period unless the moisture is detected overhead by droplets hitting the roof. those "moving" clouds and "green" moisture you see on the tv screen are not real. they are generated prediction models to give viewers a sense of realism and eventuality. in local sinkie tv you don't get to see that just regurgitated single frame snapshots stitched together from other weather news sources. most of the time on local sinkie tv, all you get is temperature and rain, cloudy or sunshine by city.
weather forecast is an art and a science. Like I said, meteorologists use trends, satellites and other weather equipment to help them. and that is the science part. that's easy. The weatherman can see the air density, air composition, weather pattern, weather phenomena and air movements. After these inputs, the meteorologists will have to interpret and translate these into weather forecasts for the layman like you. What is the point of everyday coming out with the same forecast? What is the point when the meteorologist cant translate the information to make them useful to Singaporeans?
i never uses NEA authority on weather forecast, there are so many apps on your phone that can tell the weather accurately.
NEA has discredited itself. That should never be the case as it's the authority on environment and weather in SG.
The way it is, it shows the complacency of Masagos and NEA
i rely on the weather app on the iphone. handy and 69% accurate which is good enough just to know whether rain hoodie is required.
where does the phone app info come from? isnt it from the same source...Dept of Meteorology?
If Singaporeans dont trust a SG govt agency, NEA's, forecasts, what does it say abt PAP and NEA?
why are you still relying on weather forecasts from pap and nea? the weather app has been in the palm of your hands for close to a decade.
because i want to know pap's and NEA's performance. Whether what they said are accurate, reliable and trustworthy
don't worry. they are very thrustworthy. when they say "ponding", it's quite certain that there will be flooding. it depends on how you interpret their thrusty language.
trouble is when they said it will be sunny and clear skies but we end up with thunderstorms and flooding
like that also want to kpkb. such pettiness.
