What is a Hurricane?

A hurricane (or typhoon, or severe tropical cyclone), the strongest storm on Earth, is a cyclonic (rotary) storm that derives its energy from cloud formation and rainfall, unlike frontal cyclones that derive their power from a temperature gradient. Full Article

Saffir-Simpson Scale

Category 1 – 74-95 mph (64-82 knots; 119-153 km/hr). Damage is limited to foliage, signage, unanchored boats and mobile homes. There is no significant damage to buildings. The main threat to life and property may be flooding from heavy rains.

Category 2 – 96-110 mph (83-95 knots; 154-177 km/hr). Roof damage to buildings. Doors and windows damaged. Mobile homes severely damaged. Piers damaged by storm surge. Some trees blown down, more extensive limb damage. Full Article

Tropical Cyclone Formation

Tropical Cyclone Genesis is the technical term for the process of storm formation that leads ultimately to what are called hurricanes, typhoons, or tropical cyclones in various parts of the world.

This occurs when, in the Northern Hemisphere, the Intertropical Convergence Zone, or ITCZ, shifts northward out of the doldrums and atmospheric conditions become favorable for tropical cyclone formation after about the middle of May. Full Article

REMARKS:
210900Z POSITION NEAR 20.5N 123.4E.
TROPICAL STORM (TS) 15W (HATO), LOCATED APPROXIMATELY 237 NM EAST-
SOUTHEAST OF KAOHSIUNG, TAIWAN, HAS TRACKED WEST-NORTHWESTWARD AT 11
KNOTS OVER THE PAST SIX HOURS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 
210600Z IS 12 FEET. NEXT WARNINGS AT 211500Z, 212100Z, 220300Z AND

RMKS/
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
   TROPICAL STORM (TS) 15W (HATO), LOCATED APPROXIMATELY 237 NM EAST-
SOUTHEAST OF KAOHSIUNG, TAIWAN, HAS TRACKED WEST-NORTHWESTWARD AT 11
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY (MSI) SHOWS PERSISTENT CONVECTION SHEARED SOUTHWESTWARD OF A
FULLY EXPOSED AND RAGGED LOW LEVEL CIRCULATION. THE INITIAL POSITION
IS PLACED WITH HIGH CONFIDENCE BASED ON THE MSI LOOP. THE INITIAL
INTENSITY OF 35 KNOTS IS BASED ON AN OVERALL ASSESSMENT OF OBJECTIVE
AND AGENCY DVORAK ESTIMATES RANGING FROM T2.0 TO T2.5 (30 TO 35
KNOTS). UPPER LEVEL ANALYSIS INDICATES MARGINALLY FAVORABLE
CONDITIONS WITH STRONG RADIAL OUTFLOW BEING OFFSET BY STRONG (20-25
KNOTS) VERTICAL WIND SHEAR. ALONG-TRACK SEA SURFACE TEMPERATURES
REMAIN WARM AND CONDUCIVE FOR CONTINUED DEVELOPMENT AT 30 CELSIUS.
THE CYCLONE IS TRACKING ALONG THE SOUTHWESTERN EXTENT OF A
DEEP-LAYERED SUBTROPICAL RIDGE (STR) TO THE NORTHEAST.
3. FORECAST REASONING.
   A. THERE IS NO SIGNIFICANT CHANGE TO THE FORECAST PHILOSOPHY FROM
THE LAST PROGNOSTIC REASONING MESSAGE.  
   B. TS HATO IS FORECAST TO CONTINUE TRACKING WEST-NORTHWESTWARD
THROUGHOUT THE FORECAST UNDER THE INFLUENCE OF THE STR, THROUGH THE
LUZON STRAIT BEFORE MAKING LANDFALL AFTER TAU 36 JUST EAST OF HONG
KONG. DUE TO A MARGINALLY FAVORABLE ENVIRONMENT, THE SYSTEM WILL
GRADUALLY STRENGTHEN, REACHING A PEAK OF 55 KNOTS PRIOR TO LANDFALL.
AFTERWARDS, TS 15W WILL RAPIDLY DECAY AS IT DRAGS OVER THE RUGGED
TERRAIN OF SOUTHEASTERN CHINA, AND DISSIPATE BY TAU 72. DYNAMIC MODEL
GUIDANCE HAS COME INTO BETTER AGREEMENT, LENDING FAIR CONFIDENCE IN
THE JTWC FORECAST TRACK.//
