Thanks for those stats.Without question,the most active basin in the world,even on below average seasons.

[StormingB81]

It is funny cause once I get back to the United states on the East coast I will know nothing all over again..lol just jump on here and learn about the atlantic..lol I always lived on the east coast but didnt get into the weather like this until after I left.

The Tropical Storm Risk folks released their March forecast for the NorthWestern Pacific basin.They are calling for more activity than in 2010. Click below to see forecast.

Tropical Storm Risk March WPAC forecast=28/18/8

[cycloneye]

Finnally,a invest pops up in this basin that has been very quiet so far this year in terms of TC formations.

[P.K.]

Well not particularly quiet, we've only just reached the point where on average 1.0 named storms have formed. http://agora.ex.nii.ac.jp/cgi-bin/dt/number_stat.pl?lang=en&month=3&day=23&year=2011

[Chacor]

TD in the SCS (01W), season is now underway.

[cycloneye]

We may see the second TC in the WPAC soon as 95W continues to get organized.

[Typhoon10]

Do we think it will become active towards the end of April like in 2009 with Kujira or late until July like 2010 with Conson?

[Chacor]

Welcome back, good to see you around. I think we might start to see a few more SCS storms pop up soon (we've already had two TDs, one in the SCS/one in the Philippine Sea).

[Typhoon10]

Thanks Chacor. I have been busy monitoring the earthquakes and tremors in Japan, especially as my brother and family are there. But thankfully they escaped harm in the terrible tragedy. But so many tremors keep on happening.

Also am suprised there is no excellent forum such as this one dedicated to earthquakes.

Hope your keeping well in Singapore

Had our 1st heavy rain and thunderstorm of 2011 this weekend. Getting warm and humid. Wouldnt be suprised if we see the first system develop in May. This is not a forecast, just a hunch.

I see the Biau stnry front drifting south over Hong Kong this week. That whole front is really extending quite nicely from Iwo To out your way, I wouldn't be surprised if in the next week or so we see something weak develop off of it, maybe around the PI sea, just my thought and a long way out but a thought none the less.

[StormingB81]

Looks like we may have a chance here. Invest 90W....JMA has a LPA on it and JTWC has it as poor..we shall see.

[RobWESTPACWX]

I came out with my numbers finally here. A little quiter than Avg but more intense than the last few years.

STY: 3

TY: 16

TS: 28

I talk about it near the end of the video below. Any how getting ready for the season though, already had two TD,s but I am not counting them in to my numbers.

[Typhoon Hunter]

I think we can expect a lot of activity shifted to the west of the basin this season given the expected weak/neutral La Nina. Could well mean a lot of landfalls between Taiwan, SCS and Philippines. Overall numbers I'm not sure about, probably close to normal given forecast La Nina trend.

http://www.weather.gov.hk/wxinfo/season/anlf.htm As you can see here HKO expecting between 6 to 9 TCs coming within 500km of Hong Kong which is average to above average.

Cycloneye having no activity in Wpac before May 1st is not unusual in the slightest, 95% of activity on average occurs after May 1st.

[Typhoon10]

Reports state here in Hong Kong we have had the driest March on record with only 1/3 of the normal average rainfall. Also am hearing even in the UK has experienced well below average rainfall and unseasonally high tempertures. Indeed in the UK, I believe the reservoirs are low and restriction on water usage maybe be imposed early.

Correct Typhoon 10

Warmest April on record in UK

3 May 2011 - Provisional Met Office climate figures for April 2011 indicate that the month is the warmest on record with many parts of the UK seeing temperatures 3 to 5 °C warmer than normal. The month is also the 11th driest April in the UK. These records go back more than 100 years, to 1910.

The UK average temperature was 10.7 °C exceeding the previous warmest April on record of 10.2 °C in 2007.

The warm weather was also accompanied by mainly dry conditions through the month. The UK average rainfall total was 36.7mm - 52% of the long-term average.

However rainfall amounts have varied quite widely across the UK, with parts of North and West Scotland seeing around 110% of normal April rainfall, while parts of South and East England have seen less than 10% of normal.

The dry April for many follows a dry March when less than half of the normal rainfall fell across the UK, also followed by a drier than average winter.

The dry weather this April has been largely caused by 'blocked' weather patterns across the UK. This weather pattern has prevented the usual run of westerly winds off the Atlantic Ocean, which bring rain bearing fronts.

And now we have 93W. Could be the 1st proper storm of the season for us to track!
