ZENA LEAVES ONE DEAD IN FIJI, NOW WEAKENING NEAR TONGA

One death and one missing person is being blamed on Cyclone Zena, a once Category 3 Cyclone (Fiji Scale) that pushed by Fiji overnight Wednesday in to Thursday morning.

Max winds reported in Nadi on the Fiji west coast was 35kts while Suva the capital missed the worst of the storm. The winds were not that intense but the rainfall total has been staggering.

 

In total over 600mm of precipation in the course of 5 days was reported in Nadi. This is over triple the amount the city gets in the entire course of April on average.

Western Fiji was one of the worst impacted areas. Here schools were been closed this week and much of the region was running on limited power.  Over 3,500 people were moved to evacuation shelters as dozens of homes became submerged from a Tropical depression earlier this week.

Good news is that today dry air is flowing in behind the storm bringing clearer skies to Fiji for the first time in a week. The storm itself is also weakening out quickly as it tracks in to an area of increased wind shear and dry air. Tonga could get some additional rainfall from it but nothing to severe is expected in the forecast.

 

A much more powerful Cyclone Winston hit Fiji in late February killing 44 and leaving some of the smaller islands completely devastated.

CYCLONE ZENA BRINGS ADDITIONAL FLOOD THREAT TO FIJI

The island nation of Fiji has been getting swamped by heavy rainfall this week with total precipitation numbers nearly tripling the number of average rainfall for the entire month of April.

Western Fiji is one of the worst hit areas with the city of Nadi taking the brunt of the persistent showers. Here schools have been closed this week and much of the region is running on limited power.  Over 3,500 people have been moved to evacuation shelters as dozens of homes became submerged from a Tropical depression earlier this week.

That storm system is over with but another stronger cyclone is now rolling east towards Fiji bringing with it the threat of additional heavy rains.

 

Tropical Cyclone Zena is now a Category 3 storm (on the Fiji Scale) packing winds at Typhoon strength. This is clearly indicated by a eye now forming at the storms center.

The storm is forecast to pass south of Fiji Wednesday evening through Thursday morning bringing the heaviest rainfall to the west and south of the island. Those on the islands of Viti and Levu should take extra note on the storms track.

The track could still waver and a direct hit from this developing storm would not be nearly as bad as Winston just a few weeks ago but still combined with the flooding already taking place would be a major problem for residents on the island.

Good news is that by the storm passes on Friday it should sweep in dry air from the north bringing much fairer conditions in to the region.

NWPAC outlook, 06 APR

NWPAC outlook, 06 APR

Unseasonably warm temperatures settle into all of eastern Asia as some cooler air breaks through far to the north. Dangerous heat sets up in the south region while the tropics start to show signs of weak activity. 

NORTH

Very warm temperatures are in store for much of the north region today, out ahead of a new push of cooler air located far to the north. A stationary cold front sagging over central and eastern China will be the focal point of most of the clouds and rainfall while a second, stronger, frontal system pushes down from the northwest through Mongolia, northern China and eastern Russia, trucking in some cooler air and wintry precipitation to these areas. Russia, Korea and Japan will see the best weather, with just a few scattered clouds, while the remainder of the region will see cloudy skies and occasional showers.

City High Temp C (F) Low Temp C (F) Conditions
Ulaanbaatar 4 (39) -10 (14) Snow Showers
Vladivostok 11 (52) -1 (30) Fair
Beijing 25 (77) 11 (52) Cloudy
Seoul 24 (75) 11 (52) Partly Cloudy
Tokyo 19 (66) 14 (57) Partly Cloudy
Xi’an 16 (61) 8 (46) Cloudy
Shanghai 21 (70) 13 (55) Periods of Rain

 

CENTRAL

A stalled out frontal system in the northern fringes of the region will bring some clouds and scattered thunderstorms to westernmost and northernmost locales of the central region. The moisture and energy are predominantly along this boundary, so the remainder of the region will see good weather with very warm temperatures and just a few scattered clouds.

City High Temp C (F) Low Temp C (F) Conditions
Kunming 24 (75) 12 (54) Scattered T-Storms

Taipei 29 (84) 21 (70) Fair
Iwo To 24 (75) 21 (70) Partly Cloudy
Hanoi 31 (88) 22 (72) Partly Cloudy

 

 SOUTH

Dangerous heat is once again on tap for portions of the south region, as interior sections of Vietnam, Laos, Cambodia, and Thailand see highs nearing 38C (100F) along with building humidity. There are hints that it will get even hotter in these locations as we near the weekend. A weak trough draped over the northern Philippines could bring a few scattered showers to the island of Luzon, while tropical moisture far to the south will help fire off a few scattered thunderstorms over Indonesia and Brunei.

City High Temp C (F) Low Temp C (F) Conditions
Siem Reap 38 (100) 27 (81) Fair
Ho Chi Minh 34 (93) 26 (79) Partly Cloudy
Manila 34 (93) 25 (77) Scattered Showers
Davao City 34 (93) 23 (73) Partly Cloudy
Brunei 34 (93) 27 (81) Scattered T-Storms
Singapore 33 (91) 27 (81) Cloudy

 

 TROPICS 

A very weak trough of low pressure and convergence is set up between 140E and 150E longitude, just south of 5N latitude, and will be the focus of our attention for the next few days. This is the area that has been predicted by the GFS (Global Forecast System) computer models over the past several days to become a very weak area of low pressure. This disturbance is expected to drift west-northwestward along the I.T.C.Z. (Inter-Tropical Convergence Zone) while remaining weak and disorganized. The outlook for now is for this system to bring some much-needed rainfall to parts of the Philippines next week. Let’s hope so because these areas desperately need some rain. Elsewhere across the tropics, temperatures continue to edge upwards region-wide as the longer days, and increased sun angle, allow for more sunlight to warm things up. Clouds and showers will be restricted to Micronesia, while the remainder of the region enjoys a worry-free day.
