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

1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
   TYPHOON (TY) 12W (LIONROCK), LOCATED APPROXIMATELY 269 NM EAST-
SOUTHEAST OF KADENA AB, JAPAN, HAS TRACKED SOUTH-SOUTHWESTWARD AT 06
KNOTS OVER THE PAST SIX HOURS. TY 12W HAS RAPIDLY INTENSIFIED OVER 
THE PAST 24 HOURS FROM 55 KNOTS TO THE CURRENT INTENSITY OF 100 
KNOTS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A COMPACT 
SYSTEM WITH A 12NM EYE AND NEAR-RADIAL OUTFLOW. A 240731Z GPM 89GHZ 
IMAGE DEPICTS A SMALL CORE, APPROXIMATELY 30NM DIAMETER, WITH A 
PINHOLE EYE AND BANDING FEATURE. RECENT ANIMATED WATER VAPOR IMAGERY 
INDICATES THAT TY 12W HAS BEEN ABLE TO INSULATE ITSELF AND MAINTAIN 
RADIAL OUTFLOW DESPITE WEAKENING POLEWARD OUTFLOW AND CONVERGENT 
FLOW ASSOCIATED WITH THE BUILDING RIDGE TO THE NORTH. THE CURRENT 
INTENSITY IS ASSESSED AT 100 KNOTS BASED ON DVORAK INTENSITY 
ESTIMATES RANGING FROM T5.0 (90 KNOTS) TO T5.5 (102 KNOTS). 
ADDITIONALLY, THE 24/0630Z SATCON ESTIMATE HAS JUMPED TO 104 KNOTS. 
TY 12W IS TRACKING SLOWLY SOUTHWESTWARD ALONG THE EASTERN PERIPHERY 
OF THE WESTERN SUBTROPICAL RIDGE (STR).
3. FORECAST REASONING.
   A. THERE IS NO CHANGE IN THE FORECAST PHILOSOPHY FROM THE PREVIOUS
PROGNOSTIC REASONING MESSAGE. HOWEVER, THE INTENSITY FORECAST HAS 
BEEN INCREASED SIGNIFICANTLY BASED ON THE RECENT PERIOD OF RAPID 
INTENSIFICATION.
   B. TY 12W WILL REMAIN TRAPPED WITHIN THIS COMPETING STEERING 
ENVIRONMENT WHILE DRIFTING SOUTHWESTWARD TO WESTWARD THROUGH 
TAU 36. THE WESTERN STR IS EXPECTED TO REMAIN ENTRENCHED OVER THE 
EAST CHINA SEA AND OKINAWA PROVIDING A BARRIER TO ANY SIGNIFICANT 
WESTWARD MOVEMENT. IN FACT, ALL DYNAMIC MODELS SHOW A SLOW, QUASI-
STATIONARY MOTION THROUGH TAU 48 AND SHOW NO POSITION WEST OF 131E 
LONGITUDE. TY 12W IS FORECAST TO GRADUALLY INTENSIFY UNDER FAVORABLE 
CONDITIONS TO A PEAK OF 120 KNOTS BY TAU 24.  
   C. IN THE EXTENDED TAUS, THE NEAR-EQUATORIAL RIDGE (NER) IS 
FORECAST TO BUILD TO THE SOUTH OF TY 12W WHILE A DEEP MIDLATITUDE 
TROUGH DEEPENS OVER JAPAN, ALLOWING THE SYSTEM TO ACCELERATE 
NORTHEASTWARD. WHILE THE MODEL VORTEX TRACKERS DIFFER ON THE EXACT 
NATURE OF THE TURN EASTWARD, THE TRACKERS ALL SHOW AN EASTWARD TURN 
WITH DIFFERENT TRACK SPEEDS. DUE TO THE COMPLEXITY OF THE STEERING 
ENVIRONMENT AND UNCERTAINTY IN THE EASTWARD TURN, THERE IS LOW 
CONFIDENCE IN JTWC FORECAST TRACK.//

WARNING NR 05//
RMKS/
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
   TROPICAL DEPRESSION (TD) 14W (FOURTEEN), LOCATED APPROXIMATELY 
340 NM EAST-SOUTHEAST OF IWO TO, HAS TRACKED NORTH-NORTHEASTWARD AT 
24 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY (MSI) DEPICTS FLARING, DISORGANIZED DEEP CONVECTION OVER A 
WEAK LOW-LEVEL CIRCULATION CENTER (LLCC). A 240425Z NOAA-19 89GHZ 
IMAGE DEPICTS ISOLATED DEEP CONVECTION OVER A WEAKLY-DEFINED LLCC. 
DUE TO THE PERSISTENT STRONG NORTHERLY VERTICAL WIND SHEAR, TD 14W 
HAS MAINTAINED INTENSITY AT 25 KNOTS. TD 14W IS TRACKING RAPIDLY 
NORTHWARD ALONG THE WESTERN PERIPHERY OF A LOW- TO MID-LEVEL RIDGE 
TO THE EAST.
3. FORECAST REASONING.
   A. THE FORECAST PHILOSOPHY HAS CHANGED TO A DISSIPATION SCENARIO 
AS TD 14W IS NOW FORECAST TO GET ABSORBED INTO THE LARGER, MORE 
DOMINANT LOW PRESSURE AREA (INVEST AREA 92W) TO THE NORTH.
   B. TD 14W IS EXPECTED TO CONTINUE TRACKING NORTH-NORTHEASTWARD 
THROUGH THE FORECAST PERIOD AS A WEAK TROPICAL DEPRESSION. HOWEVER, 
THE SYSTEM IS EXPECTED TO TRACK INTO THE SOUTHEAST QUADRANT OF THE 
LARGER, MORE DOMINANT LOW PRESSURE AREA (INVEST AREA 92W) AND 
DISSIPATE RAPIDLY. MSI IS ALREADY SUGGESTING THAT TD 14W IS GETTING 
PULLED INTO THE SOUTHERN FLANK OF THIS LOW PRESSURE AREA AS 
EVIDENCED IN MSI, WHICH SHOWS EXTENSIVE LOW-LEVEL CLOUD LINES 
WRAPPING INTO THE BROADLY DEFINED LLCC OF INVEST 92W. DYNAMIC 
GUIDANCE SUPPORTS THIS SCENARIO AND TRACK WITH GOOD CONFIDENCE.//
