The Atlantic and East Pacific are both quiet today, with no tropical cyclones active or expected to form in the next five days. There is only one tropical cyclone worldwide – Typhoon Lan in the Western Pacific, which could pose a possible threat to Japan later this week.

As of 00:00 UTC Wednesday, Lan was centered near 12.1°N 132.3°E. Maximum 1-minute sustained winds were 65 knots (75 mph), with an estimated minimum pressure of 977 mb. Lan is likely to strengthen into a strong typhoon by Friday before weakening begins, and is likely to weaken slightly but could strike Japan as a typhoon. Residents of Japan should closely monitor the progress of Lan.

I will be back with another post on Thursday, as there is not much to discuss in the tropics at the moment.
