for the latest, here's our meteorologist sayaka mori. >> hello there. as we have been reporting, there are a couple tropical disturbances in asia. this is a tropical depression, could become a tropical storm in the next 24 hours and projected to make landfall in southern vietnam tonight. heavy winds, are on the way. northern areas could be hit by heavy rainfall. now a more active system is on the way to the philippines. we have a strong typhoon. named haiyan. this is number 30 tropical named storm. we haven't had over 30 tropical storms or typhoons so far this year. excuse me, since 1994. so this year is very active over the tropics. now this one will likely become a violent typhoon by the time it reaches the midsection of the philippines. wind gusts could be 270 kilometers per hour, strong enough to destroy houses and water and electricity could be unavailable for several days. not just winds but also drenching rain is on the way to affect the midsection of the philippines as we go into the latter part of the week. so critical situations are expected t
