Typhoon Evan (04P) has moved into the Samoan Islands, becoming a typhoon in the process. The latest Joint Typhoon Warning Center (JTWC) forecast shows 90 knot sustained winds, with gusts to near 110 knots. An increase in wind speeds is expected to reach 110 knot sustained winds, with gusts to near 135 knots over the next 48 hours. The forward motion has slowed, which will allow this devastating typhoon to remain in the general area of these small islands for nearly 24 hours. This in turn will keep very strong gusty winds, flooding rainfall, and pounding surf effecting these islands.

Already there have been reports that Evan has pounded the area, with at least 2 deaths as of the time of this writing. The Samoan capital of Apia, has reported sustained damage to homes, many of which have been flattened. Power is out in many areas, with the storm having made a huge impact on vegetation and infrastructure. Trees are down in most areas, piling up on roads…making relief efforts very difficult. The population of Samoa is approximately 183,000, while American Samoa has about 55,000 people.

When this strengthening tropical cyclone finally leaves the Samoan Islands behind, it’s forecast to take a direct bearing on Fiji. The JTWC projected path of Evan, takes it over a small part of the small island of Vanua Levu, and then directly through the middle of Fiji. The forecast calls for this storm to finally begin weakening just before arriving over those small islands. Nonetheless, it will still bear typhoon strength winds…even after it pass Fiji. Evan is forecast to arrive over this area between December 16-17. This part of the forecast is far enough out into the future, that there may be changes in strength, and the exact track over the next few days. Vanua Levu and Fiji should expect very heavy weather, and be preparing for the worst, despite these possible changes.
