OMAHA | Oriental Ocean Weather Services


Recommended Posts

The Oriental Meteorological, Atmospherical and Hydrological Administration, abbreviated as OMAHA, is a joint meteorological organization between several nations in the vicinity of the Oriental Ocean. Formally established on 28 August 2017 in Waipahu, @Kualoa, founding members included Kualoa, @Andalla, and the @Sunset Sea Islands. OMAHA was established to provide its member states with a quick and reliable source for weather reports, usually regarding tropical cyclones. Though OMAHA does not hold national status within any nation, it represents a partnership between the national meteorological agencies of its member states, and is recognized as the foremost authority on weather information within the vicinity of the Thalassan and Southern Oriental Oceans.

OMAHA officially monitors tropical cyclones and weather disturbances that occur within an area of nearly 60 million square kilometers, bound by the following coordinates:

  • 45°S 105°E
  • 20°S 105°E
  • 20°S 150°E
  • 20°N 180°W
  • 20°N 120°W
  • 20°S 120°W
  • 20°S 180°E
  • 45°S 180°E

TROPICAL DEPRESSION, ten-minute sustained winds of up to 63 km/h (34 knots)

TROPICAL STORM, ten-minute sustained winds of 63-88 km/h (34-48 knots)

SEVERE TROPICAL STORM, ten-minute sustained winds of 89-118 km/h (48-64 knots)

TYPHOON, ten-minute sustained winds of 118-220 km/h (64-119 knots)

SUPER TYPHOON, ten-minute sustained winds of 220 km/h (119 knots) and up.

TROPICAL CYCLONE ADVISORY

September 17, 2017 [ 2:54 AM SST / 3:54 AM AST ]

A low-pressure area initially detected roughly 800 kilometers directly south of Burkini has intensified into a Tropical Storm (TS) and has been assigned the name Annemarie (international name Denisa).

Tropical Storm Annemarie holds the distinction of being the first tropical cyclone officially named and monitored by OMAHA, while the first list of storm names was announced last week.

As of September 17 at 2:00 AM SST (3:00 AM AST), TS Annemarie recorded ten-minute sustained wind speeds of 65 km/h and was moving east at 24 km/h. The cyclone is expected to intensify into a Severe Tropical Storm (STS) within 18 hours, with expected light showers over Bastion Island as it intensifies.

Weather forecasts show favorable conditions for further development of the storm over the next 2-4 days, possibly bringing heavy showers to the far north of the @Sunset Sea Islands.

TROPICAL CYCLONE ADVISORY

September 18, 2017 [ 11:27 PM SST / 12:27 AM (+1) AST ]

Tropical Cyclone (TC) Annemarie has intensified into a Severe Tropical Storm (STS), bringing light showers over Bastion Island with ten-minute sustained wind speeds of 91 km/h. It is currently located approximately 600 kilometers west-northwest of Bastion Island, travelling east at 19 km/h.

Wind forecasts place STS Annemarie at a high chance of changing course slightly north, keeping the Bastion Reservation City away from possible heavy rains within the next few days. The storm is expected to further intensify, reaching peak intensity within 3-4 days, after which it will make landfall in Andalla after a week.

At around 10:15 PM SST (11:15 PM AST), Annemarie weakened shortly, only to re-intensify once again. A storm notice is expected to be issued over the northern areas of the @Sunset Sea Islands.

TROPICAL DEPRESSION "HAPAI" UNDER MONITORING

hapai_td.png

Tropical Depression "Hapai" was recently placed under monitoring status by SUMATRA. With 10-minute sustained winds of 47 km/h, it is unfortunately expected to strengthen.

Recent calculations show that Hapai is most probably going to hit KUALOA, and is moving SOUTH-SOUTHWEST at a speed of 36 km/h.

Kualoan residents are highly-encouraged to be prepared, if ever, and to stay in-touch with SUMATRA announcements and bulletins. Though it is only a very slight possibility, SUMATRA has also warned @Arstotzka regarding the cyclone.


As Hapai makes its way towards Kualoa, Gyukudo is continually weakening and has been reclassified to a severe tropical storm. Minor damages were reported when it made landfall in Futanarien. It continues to head north-northeast but is not expected to hit @Iverica or @St Francoisbourg.

Another LPA is under monitoring, 730 kilometers southwest of Liberty Island. If it intensifies into a tropical depression, it will be given the name Ioana.

"HAPAI" NOW TYPHOON, NEARING KUALOA

hapai_td.png

As predicted, it has been confirmed that former Tropical Depression "Hapai" is heading on a course STRAIGHT FOR KUALOA. In an unexpected turn of events, Hapai quickly intensified several categories up, being reclassified as a TYPHOON.

In a bulletin issued 6PM Thursday, SUMATRA said that it expects Hapai to further intensify. Readings at the time detected 10-minute sustained winds of 134 km/h. It was moving east-southeast at a speed of 61 km/h.

Minor rains are expected to hit @Arstotzka, however Hapai is not expected to make landfall there.

ALL KUALOAN RESIDENTS ARE HIGHLY ADVISED TO PREPARE FOR EVACUATION TO SAFER GROUND, TO SECURE PERSONAL BELONGINGS AND TO KEEP UPDATED WITH THE LATEST SUMATRA BROADCASTS AND BULLETINS.

OOC: Yikes. It has been, like, three weeks. My computer broke down at the wrong time. Anyway, I'm making a comeback for this week on my mom's computer, and hopefully after this week my computer will be repaired.

As for the typhoon, imagine this post was made in the early morning of October 27.


"HAPAI" CONTINUES TO INTENSIFY, EVACUATION PROCEDURES UNDERWAY IN KUALOA

With several days expected until Hapai hits, the Kualoan government in cooperation with several humanitarian organizations have begun evacuation. More and more evacuation centers and shelters are being hastily set up. The Kualoan government has also begun distributing first-aid, relief aid and pamphlets regarding the current situation. A significantly large military and police force has already been deployed in many parts of the nation.

All ships near Kualoa have been ordered to either seek shelter at the nearest Kualoan port or clear out of the area. The nation and its vicinity will be declared a no-fly zone after the midnight of October 27.

Meanwhile, Hapai continues to strengthen, with 10-minute sustained winds of 148 km/h. Current estimates indicate that it would make landfall within 3 days.

ALL KUALOAN RESIDENTS ARE HIGHLY ADVISED TO FOLLOW EVACUATION PROCEDURES TO THE NEAREST SHELTER OR SEEK HIGHER GROUND.

OOC: Time travel again: Late night of October 28.


"HAPAI" CONTINUES TO INTENSIFY, EVACUATION WELL UNDERWAY

As expected, Typhoon Hapai continues to intensify with 10-minute sustained winds of 161 km/h. Kuala government reports state that evacuation is "well underway", with significant portions of the population in shelters or high ground. Basic needs and equipment have been distributed to a majority of the population.

The last aircraft in the area, Air Kualoa Flight KU 184 landed at 12:08 AM on October 28, and the no-fly zone was implemented. A large number of ships at sea have docked at Kuala ports, however some are still far out.

TROPICAL DEPRESSION "SAIGAI" RECLASSIFIED TO TROPICAL STORM

Saigai, which has formed north-east of Burkini, leaves the region northwards with minimal effects on the surrounding islands. The intensifying phenomenon has been reclassified to a tropical storm reaching sustained wind speeds in the low-to-mid eighties. The UBPSSIF coast guard is alerted. Inhabitants of northern Thalassa and the Dobbarrier reef are advised to keep windows closed when the storm makes landfall.

"SAIGAI" ESCALATES INTO SEVERE TROPICAL STORM

The northbound storm Saigai continues to accelerate. Satellite footage confirms that the storm reached sustained top speeds of over 100 km/h, thereby being reclassified to a severe tropical storm. Coast guard is on high alert, inhabitants of the Dobbarrier reef and the Futari islands are advised to check water and food reserves. When the storm makes landfall, please stay away from windows and doorways to avoid potential shrapnels.

TYPHOON "SAIGAI" TO HIT NORTHERN THALASSA

Saigai continues to gain strength as it closes in on northern Thalassa. It is expected to make landfall with sustained speeds of over 150 km/h, making it one of the most dangerous storms in recent history. SSI-run emigration centres are organising emergency transports and the coast guard is working hard to spread the message of the inbound calamity throughout the cities and villages of the archipelago. Everyone is advised to seek shelter, follow emergency service personnel instructions and keep their radios on at all times. Should you be unable to leave your house, if possible, seek shelter on rooftops to make it easy for rescue helicopters to spot you.

Once more: Saigai poses imminent danger to you and your loved ones. Seek shelter and follow emergency instructions at all costs. Prepare for evacuation immediately.
